to improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. each of the rougher circuits had a dedicated regrind and cleaner circuit. the advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. with this process, copper was recovered first with mbs depression of lead, zinc and
pug mills are a key piece of equipment in the copper smelting process, serving to mix and condition several components (copper concentrate, flux, reverts, matte recycle, and dust recycle), for reintroduction into the smelter.. material handling. in addition to our pug mills and ore drums, feeco can supply the necessary material handling equipment to transport copper around the processing facility.

heritage pass offers discounted tour of silverton’s mining history “most of the equipment in underground hard rock mining now is pneumatic — ran by air.” zinc and copper will
copper-zinc ores usually chalcopyrite, sphalerite and iron sulphides are present with this type of ore. gangue minerals are typically various silicates, carbonates, and often talc the latter which presents flotation challenges.
second, liberated contaminants, specifically sphalerite, were observed in the copper concentrates. a relationship between copper deportment as chalcopyrite and bornite in the feed and zinc contamination in the copper concentrate was observed. activation of sphalerite through dissolving of covellite and possibly tennantite/enargite is hypothesized.
