At the Dubai Mining Show we were honoured to have been mentioned for our contribution towards the Ariab project! The project began with metallurgical testing by APT to find an optimal treatment route for this difficult ore. In conjunction with Ariab’s own metallurgists a flowsheet was formulated to overcome the challenges, after which APT designed and built a plant to achieve the desired result. APT also installed the plant and commissioned it. The process guarantee for the plant was a high bar of 93% gold recovery, and that was not only achieved, but exceeded. The salient details were a throughput of 35tph with a CIL residence time of 24 hr at a grind of P80 75 microns. Pressurised elution and carbon regeneration were included in the package, along with a cyanide destruct module. The installation was a success because it incorporated leading edge technology at every step, especially the extremely efficient mixing resulting from APT’s proprietary and patented TriTank system.
APT TriTank CIL Plants: The Best Thing Since Sliced Bread
The Best Shaped Reactor
The triangular shape of each sector, together with some special base additions, results in very high mixing rates far better than cylindrical tanks.
Compact Shape and Small Footprint
There is no CIL system more compact than the APT TriTank. Apart from using less ground area, the unit is far easier to surround with a protective berm as required by law in many countries.
Immense Strength
The APT TriTank structure is effectively cross braced sixfold! There has never been a collapsed TriTank and there never will be.
Top to Bottom Mixing
The slurry in an APT TriTank is mixed vertically from top to bottom, not horizontally around. This results in excellent mixing for dissolution, and also eliminates segregation of carbon from top to bottom.
High Efficiency Interstage Screening
As the TriTank sectors are adjoining, the radial walls can be used for interstage screening. APT uses wedgewire screen panels at the top of each wall as the perfect solution to interstage carbon screening. The top to bottom motion of the slurry continually sweeps the screens clean, resulting in faultless operation. When it comes to maintenance, the screen panel housing design incorporates a parallel groove which allows for the fitment of a secondary panel, which can be put in place whilst the primary panel is removed for cleaning and maintenance. This means there is no interruption to operation.
Increased Dissolved Oxygen Levels
Due to the top to bottom mixing, the slurry is continually being exposed to air at the surface of the tank resulting in an increase of dissolved oxygen levels of up to 30%!
Faster Dissolution Rates
The excellent mixing coupled with the elevated dissolved oxygen levels results in faster dissolution rates and higher overall recovery. This also leads to the possibility of a smaller CIL plant installation.
APT Manufactures and Installs
The APT TriTank manufacture has evolved to the point where the precision made components are shipped to site in containerised cassettes. The APT team then rapidly assemble the tank on your site free of hassles. There is no faster installation available!
Available in Stainless Steel
Speak to our engineers about specialised applications - the APT TriTank is an ideal reactor for most chemical reactions.
Behind the Scenes at APT
Meetings play an important role here at APT, not only between us and our clients but also between us as a team. APT’s team works closely together to ensure each plant that leaves our Head Office has been designed and manufactured with the utmost attention to detail, from start to finish. Our plants are efficient, cost effective, and manufactured in-house to ensure our high quality standards are maintained!
Never a Better Time than Now! | Start Mining
The gold price has just crossed US$2000 per ounce. The demand for minerals is very strong and prices are good. Now is the time to climb in and take advantage.
TIME is the operative word, and we at APT are ready to react to help you get into production FAST. But time doesn't end there, you need to stay in production over time, and that means installing high quality equipment that you can maintain easily. Everything wears, we know that, and that is why APT provides not only quality equipment from the outset, but also spares and consumables packages so that your equipment can be kept running, day after day.
It would be a tragedy to start a good venture with cheap rubbish that will soon fail. Instead, it is far better to begin at a smaller scale that you can afford, and use your profits to grow your venture properly and professionally. APT supplies a range of small-scale starter plants specifically for this, made to the same high quality standards we’re known for, because we know what it takes to be successful.
APT - it is time for success.
Mining in North Africa | APT TriTank Cyanidation Plant
On site in North Africa with a magnificent TriTank Cyanidation Plant, manufactured, installed and commissioned by APT.
APT designed the TriTank system for gold recovery via CIL/CIP. The TriTank incorporates the traditional 6 cyanidation tanks into one single tank, partitioned into 6 individual sectors. The result? Less steel required for manufacture (and thus lower capital cost), smaller footprint, easier materials transfer between sectors, enhanced mixing characteristics, and more. Let us know if you are interested in setting up a CIL/ CIP system, and we would be happy to assist you and introduce you to the TriTank.

What is the Correct Size to Start Your Mine?
The correct answer in all cases is SMALL
1. If you are a new small-scale miner:
There is a lot to learn and you will find that there are many demands upon your startup capital. None of that money comes back until you sell your first production, so it makes sense to get your plant in and operational as fast as possible.
So what is the right size?
If your ore is very rich, for example 10 grams of gold per tonne or more, you could go as small as 500kg per hour and use APT's RD5 plant with GoldKacha Mini.
If your ore is 5-10 grams of gold per tonne or more you could start at 1tonne per hour and use APT's RD15 with a GoldKacha.
If your ore is in the range of 3-5 grams of gold per tonne you will need to start at 5 tonnes per hour or more and use APT's RD50 with three GoldKachas.
2. If you are a large operator wanting a medium-to-large scale installation:
Although APT manufactures and installs plants all the way up to 150 tonnes per hour capacity it is very useful to begin with a small pilot installation even whilst the larger plant is being manufactured. There are several reasons to justify this:
Firstly, as a proof of concept to justify the chosen metallurgical process and throw up any optimisation opportunities that can be incorporated into the large plant timeously.
Secondly, to check up on the actual expected recovery as well as the variability of the different sections of the ore body. By building back a head grade from production, nugget effect is minimised and the grade is as accurate as possible.
Thirdly, it allows for easy on-the-job training and gaining operational familiarity.
Fourth, large product samples can be generated for offtaker testing, etc.
Finally, even a small pilot project can qualify as a 'producer' to help with permit security.
So what is the correct size?
The minimum pilot plant that will produce reliable data is about 500kg per hour, but often 1tonne per hour is chosen. The process can be as simple or complex as necessary since APT produces milling, gravity, cyanidation and flotation modules at small size. All minerals can be catered for, and once installed the pilot facility can remain as an R&D bed.

A Golden Update from West Africa!
APT's GoldKacha Concentrator has once again shown what an excellent solution it is for mercury-free gold recovery. We received these brilliant results from one of our valued clients using the unit in West Africa.
One of the factors that makes the GoldKacha more effective than other types of bowl concentrators is the specialised riffle design, which allows material to be recycled internally before it leaves as tailings, meaning more chances to catch the gold!
With the introduction of our GoldKacha Mini, this technology is even more accessible for small-scale miners and we look forward to seeing the results achieved!
