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.

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.
