Abstract: Methods and systems for preparing ore for precious metal extraction is provided. For example, a method comprises crushing ore; grinding the crushed ore; screening the ground ore to separate ore particles into a first group of large ore particles and a first group of small ore particles; crushing the first group of large ore particles; screening the crushed ore to separate into a second group of large ore particles and a second group of small ore particles; separating the second group of small ore particles from the screen into a third group of large particles and a third group of small particles; milling the third group of large ore particles; separating milled particles into a fourth group of large particles and a fourth group of small particles; and sending the third and fourth group of small particles for further metal extraction processing.

Abstract: An adsorbent composition comprising particles consisting of a core which is at least partially coated with an adsorbent material is disclosed. The core is selected so that it has at least one of: (i) wear resistance; (ii) resistance to corrosive conditions; (iii) at least one thermoplastic material; and (iv) a low porosity. A suitable core material is polystyrene. Adsorbent materials suitable for the coating include activated carbon and metal oxides such as silica and alumina. The adsorbent composition may be used for the adsorption of metals and metal ions in ore processing, for instance for the separation of precious metals such as gold.

Abstract: A stabilization process for an arsenic solution comprising thiosulfates, the process comprising: acidifying the arsenic solution to decompose the thiosulfates, to yield an acidified solution; oxidizing the acidified solution to oxidize residual As3+ to As5+ and reduced sulfur species to sulfates, to yield a slurry comprising elemental sulfur; separating elemental sulfur from the slurry to yield a liquid; oxidizing the liquid to oxidize residual reduced sulfur species, to yield an oxidized solution; and forming a stable arsenic compound from the oxidized solution.

Abstract: A process is provided for separation of at least one metal sulfide from a mixed sulfide concentrate. The process includes: subjecting the mixed sulfide concentrate to flotation in which at least one sulfide including antimony, arsenic and a first metal is floated and at least one sulfide including a second metal is depressed. The flotation yields a first metal concentrate having the at least one sulfide including antimony, arsenic and the first metal and a second metal concentrate having the at least one sulfide including the second metal. The first metal concentrate is leached to yield a further concentrate and a leach solution. The further concentrate includes the first metal and the leach solution includes soluble antimony and soluble arsenic. The process further includes oxidizing the leach solution to yield an antimony precipitate and an arsenic solution, and forming a stable arsenic compound from the arsenic solution.
