Gold Section
Gold and PGM metals are leached and precipitated from Gold Mud produced in silver electro-refining. In hydrometallurgical processing Gold & PGMs are separated utilizing sequential leaching, precipitation and filtration steps.
Its main advantage for the producer is that it offers a high direct recovery rate as well as a very low inventory of metals bound in the process. PGMs are precipitated as a concentrate and sold in the market as PGM Concentrate.
