含貴金屬礦石渣漿泵浮選技術(shù)
1浮選技術(shù)一般用于何種貴金屬礦石的分選?
浮選是處理含貴金屬礦石的重要方法之一，一般用于處理下列礦石:①含金黃鐵礦(采用混合浮選);②含金、銀的銅、砷、鉛、鋅等硫化礦;③含鈀與鉑的硫化礦;④含碲化物的氰化尾礦:⑤含碳與石墨質(zhì)的貴金屬礦石。貴金屬硒化物的含最通常很低，在多金屬礦石浮選時(shí)，部分進(jìn)入銅精礦，火法冶煉富集于金屬銅中，以后在銅電解時(shí)西化物則殘留在陽極泥內(nèi)，再?gòu)年枠O泥浮選出硒化物。
2自然金的可浮 性如何?渣漿泵
金是一種易浮礦物。在原生的金礦床中，自然金常與黃鐵礦、黃銅礦、方鉛礦、閃鋅礦，毒砂等硫化礦物共生。這些礦物同是易浮礦物，并能形成穩(wěn)定的礦化泡沫，是金礦物最理想的載體礦物。通過浮選可以最大限度地使金富集到硫化物精礦中。自然金表面具有較好的疏水性，用黃藥等硫化礦捕收劑均能浮選，載體浮選、離子浮選等微細(xì)粒浮選方法均可以回收微細(xì)粒級(jí)的自然金。
Flotation technology of slurry pump for precious metal ore
1. What kind of precious metal ore is flotation technology generally used for?
Flotation is one of the important methods for the treatment of precious metal ores. It is generally used for the treatment of the following ores: ① gold bearing pyrite (mixed flotation); ② copper, arsenic, lead, zinc and other sulfide ores containing gold and silver; ③ sulfide ores containing palladium and platinum; ④ cyanide tailings containing telluride; ⑤ precious metal ores containing carbon and graphite. The content of precious metal selenides is usually very low. During the flotation of polymetallic ores, some of them enter into copper concentrate, which is enriched in copper by pyrometallurgy. Later, during the copper electrolysis, the selenides remain in the anode slime, and then the selenides are extracted from the anode slime.
How about the floatability of natural gold? Slurry pump
Gold is a buoyant mineral. In the primary gold deposits, natural gold often coexists with pyrite, chalcopyrite, galena, sphalerite, arsenopyrite and other sulfide minerals. These minerals are both easy to float and can form stable mineralized foam. They are the most ideal carrier minerals for gold deposits. Gold can be enriched to sulfide concentrate by flotation. The surface of natural gold has good hydrophobicity. It can be floatated by pyrite collectors such as xanthate, and can be recovered by carrier flotation, ion flotation and other micro fine flotation methods.
