Mining Equipment Out This Week: APT TriTank TT20

The past few weeks have been nothing short of a whirlwind at our offices and we have loved every minute! The buzz of the welding coupled with the hum of the forklift and chatter of the workers just added to the excitement in the air, it is the middle of the year and 2018 is in full swing.

Shown above is a picture from our Instagram live platform (be sure to give us a follow on @aptprocessing for up-to-the-minute updates), of one of our most recent plants, and favourites to build, the APT TriTank TT20 CIL circuit. We manufactured two TT20's for this particular project, along with a feeder, conveyor and milling module. The plant was built and pre-assembled in our offices in Johannesburg, then freighted to its final destination in Southern Africa. From this point on, most of us do not see the plants until they are fully installed on site, so we look forward to the installation and commissioning updates as much as you.

  

As soon as the plants arrive on site, our on-site team gets to work efficiently. This is what they did after a day or two, and we look forward to seeing the end result!

Upgrading Concentrates before Smelting: mining equipment on site

One of the final stages of any gravity recovery circuit is upgrading the concentrates before smelting, often carried out on a shaking table. The material is first screened to prevent particle size vs. SG interaction, and then passed onto the vibrating table deck for the final gravity separation. The light sands are washed off the side of the deck, whilst the heavy minerals migrate to the centre, forming that sought after yellow gold line. APT have manufactured, installed and commissioned various gold mining plants. This video was taken at one of those mine sites and shows the shaking table in particular:

On A Small Scale Gold Mine Site: APT RG30 3tph scrubber & Goldilox

Here is a raw snippet from our time on a small scale gold mine site with APT's Golidlox safe concentrates storage system operating in conjunction with the RG30 Scrubber for optimal mineral recoveries. The RG30 is a 3tph alluvial gold processing plant, available as either a standalone set-up or in trailer version. Our mining equipment has been designed in such a way that various components can be seamlessly coupled together as per your requirements; visually and operationally pleasing.

The Goldilox part of this alluvial processing plant facilitates an automated flush of the GoldKacha concentrator, and stores the gold bearing concentrates in a secured lock box for collection at the end of the shift. Now you can have peace of mind that your gold is right where you left it. Secure, safe and efficient.

Mining Equipment Testimonials: APT modular mining equipment

APT have always taken the approach of providing solutions to problems faced in the industry, rather than simply providing equipment, and we apply this ideology throughout our range from the ground up. A large part of this is taking on client feedback, listening to what you need and want and being able to produce that. We wanted to feature that feedback in this article, as a testament to our valued clients, the mining equipment and the hard work and dedication that comes from within the APT team. These testimonials are for the RG scrubber and over time we will be covering the entire APT mining equipment range. "The combination of the RG100 with the Knelson MD12 concentrator is an excellent match. Even the most stubborn clays are disintegrated by the autogenous scrubbing action in the drum section (assuming correct feed rate), and this plant combo is excellent for processing of eluvial and alluvial ores, especially smaller high value deposits." - J. Duguid (Managing Director, Stillram Mining Co.p/l).

Below is an RG100 scrubber coupled with the FLSmidth Knelson concentrator for optimal gold recovery.

 

"We have been using the RG200 Scrubber to process bauxite at our mine for 3 years. This machine has been used on a daily basis, and handles a constant feed of 15-20tph. It successfully breaks down the tough clay content and thoroughly cleans any hard rock content within the feed material. The RG200 very successfully screens and separates our larger material (-3mm). We have had good after sales service from APT and are satisfied with the plant supplied." - J. Meikle (Director, Mina Alumina Lda)

Above is an RG100 scrubber, and below is an RG200 scrubber.

 

The above pictures show 2 APT RG combo plants on differing mine sites. The set up is neat and allows for seamless installation, commissioning and operating.

Thank you to our clients for your support and to the APT team who make it all possible!

TT20 Small Scale Cyanidation Plant: on a mine site with APT

Here we are taking you on a quick walk and talk through of the location of our latest 1.5tph small scale cyanidation plant installation. Positioned near a historical stamp mill, the plant will be processing dump material through a mill and TT20 cyanidation circuit.

The APT TriTank was designed several years ago and adopted an unconventional approach starting with its triangular design. This results in more ideal mixing leading to superior solid suspension and gold dissolution and higher dissolved oxygen levels. The well-sealed motor design ensures oil spillages into slurry are minimized and thus metallurgical performance is enhanced. The design also uses a smaller land footprint and less construction materials. The Tritank can be relocated to multiple sites, reducing "mine-to-process" transport costs. 

These tanks have a wide range of applications and can be setup for Carbon-In-Pulp (CIP), Carbon-In-Leach (CIL), or Carousel operation. The mixing profile is so much better in tests and in practice, that the design has completely eliminated the need for baffles which present a large amount of hassles in circular tank operation. 

True to APT's style, the TT20 has a host of benefits in keeping with the larger scale TriTank cyanidation modules. Below are some of these benefits:

Indeed, there is nowhere to put them. The mixing mechanism results in more rapid leach kinetics for a smaller plant or a higher throughput.

This allows pulp flow to be directed from any sector to any sector, even from stage 1 to 6, without long launders. This allows any sector to be taken offline for maintenance, or the plant to be operated in carousel mode.

What is conventionally achieved through 6 separate, large tanks is now achieved through one tank sectorialized into 6 compartments.

The hexagon shape results in 27% less footprint than 6 circular tanks of equivalent volume (1/1 H/D ratio). This impacts ground space but also on foundations, bunds, decking, cable runs & pipe runs, & more.

Mining Week in Review: frequently asked questions

As mining equipment engineers and suppliers, we often get asked various questions relating to our mining equipment as well as common themes or misconceptions within the mining industry as a whole. We often answer these questions on our social media pages, namely Instagram and Facebook, but incase you missed it here is the past mining week in review!

Q: “What recovery can I obtain using your plants and/or processing equipment?” ⠀⠀⠀⠀⠀⠀⠀⠀

A: How well a particular ore responds to gravity recovery is entirely dependent on it’s metallurgical properties. We recommend carrying out prior mineral testwork through our associated laboratory, Peacocke and Simpson, before deciding on a plant process design as recoveries can vary greatly. The ore dictates the terms, and will determine the exact flow of equipment required to obtain the best possible recovery. Visit the Mineral Testwork page on our website here to find out more. 

Q: We’re often asked to send a full catalogue and price-list for all our gravity recovery plants. Why is this not possible? ⠀⠀⠀⠀⠀⠀⠀⠀⠀ A: APT currently offers over 100 different combinations of machines/plants to suit your particular ore and testwork parameters. Hence we prefer you give us detailed information at the time of enquiry. We will then be able to select the most relevant solution for your needs and quote accordingly. 

We are continuously looking to update our website with information that is helpful and relevant to the mining industry today. Should you have any other questions, we are happy to help- simply fill in our contact form here or email us on info@aptprocessing.com and we'll get back to you shortly.

Small Scale Alluvial and Hard Rock Mining Equipment: APT RDGK

This equipment focus will feature APT's RDGK alluvial and hard rock mining plant, a small scale mining solution incorporated within APT's GroundBreaker range. "I have worked with a team to make the RDGK15 into a very competent gold recovery pilot plant. The gold recovery plant is highly portable and was run as a product/pilot plant. The percentage recovery of gold was greater than suggested from constant supervision of the RDGK15 hard rock and concentrator combo unit. The simplicity of the GoldKacha concentrator makes it a very easy unit to achieve regular good percentage gold recoveries." - APT client, Zimbabwe

In a nutshell, the RDGK is a complete hard rock gravity recovery solution, combining the APT impact crusher and GoldKacha concentrator in one neat, modular package. In keeping with APT's philosophy, the RDGK has been designed in such a way that you can add onto the individual components as you grow or as your resource requires. As such, there are several variations available depending on your requirements and affordability. Below are some of those versions including the Goldilox, incorporating the gold storage box, and the RDGK trailer plant for optimal mobility. If you have any questions, comments or concerns, we are always here to hear them so feel free to email us on info@aptprocessing.com or contact us here.

Below is the diesel powered RD15 Impact Crusher, with a capacity of 1.5 tonnes per hour. Completed and ready for shipment. As you will see, it has been designed such that the GoldKacha can be fitted beneath the crusher should the need arise. The GoldKacha has a capacity of up to 3 tonnes per hour.

Below is an RDGK with automated and secure Goldilox™ system. A dry run is always completed before any plant heads out to site, with this one in particular heading off to it's new home in Southern Africa. The Goldilox™ system ensures there is no access to the concentrates generated during the run cycle. All concentrates are automatically discharged at pre-set intervals into a locked concentrate box sitting beneath the GoldKacha. The security cage and concentrates box are unlocked at end of day and the concentrate box is taken to a secure area for upgrading and smelting of the cons. The run time interval is pre-set by the mine operator and password protected. Goldilox™ also logs run time to allow owners and operators to see a record of daily use and total use. Combined with APT’s alluvial and hard rock plants, small scale miners are now able to run a secure operation on a start-up budget with the peace of mind, knowing gold recovered remains yours.

Below, manufacture and pre-assembly is complete on APT's 1.5tph hard rock and spirals processing plant, built in a record time of just 6 weeks.

 

Here is a video of our trailer version of the RDGK, showing exactly how it operates.
