A MERCURYFREE METHOD OF GOLD RECOVERY Promoting viable handson solutions is the goal of our Stop Mercury Project, and direct smelting is a mercuryfree method of gold recovery from highgrade concentrates. It's a simple and costeffective method that can be done in the field with very little eduion, equipment or expertise.
Mixed REE mineral concentrate (typically 2040% TREO grade), high LeCe content, requires substantial processing before suitable for feed to rare earth separation plant : Product Payability: 7080% payability as mixed Rare Earth oxide/carbonate/chloride: 3540% payability as a mineral concentrate: Processing Environmental: Nonradioactive tailings Solution treatment and .

· Miners wash the heavy mineral concentrate with water, as the wet stones are vibrated over a grease film. The wet minerals will repel the grease and continue on to waste, whereas diamonds will remain stuck in the grease. The grease mix can then be scrapped and boiled off to remove the traces of grease and leave mostly diamonds behind.
In this study, gold recovery by direct smelting of concentrates and that via amalgamation, retorting and smelting were compared in terms of recovery and time utilised for the operation. Laboratory investigations conducted on alluvial, free milling and sulphidic ores indied recovery of about 99% for direct smelting. Under controlled laboratory

(d) The % Weight Recovery is equal to the % Weight of the concentrate in Table 1. It can also be calculated from the assay values given in the table, as follows: % Weight Recovery = 100·( )(20 – ) = 10% (e) The Enrichment Ratio is calculated by dividing the concentrate assay in Table 1 by the feed assay:
· Heap leaching: Heap leaching is a process commonly used for the recovery of precious metals (gold and silver), and less commonly for base metals and uranium, from amenable, oxidised lowgrade ores, or occasionally from previously processed tailings. Amenable ores are oxidised.
