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:
