Lead-Bismuth Flotation Mineral Processing & Metallurgy

Thus, the copper concentrate will not have penalties for bismuth. Ideally, the bismuth content must be less than 1000 ppm. Considering the fact that lead and bismuth are very close in the periodic table (number atomic: 82 Pb, 83 Bi), they can have similar behaviour during flotation. It means that collection and depression is very similar for both.

Tungsten Metallurgy Mineral Processing & Metallurgy

Flotation of Tungsten Ores. Flotation has a very important application in treating the more complex tungsten ores, particularly those containing sulphides. Many of the tungsten ores contain pyrite, arsenopyrite, molybdenum, bismuth, copper, lead, and zinc minerals all of which would contaminate gravity tungsten concentrates.

Bismuth Dissolution at Smelter

The high silver content, of approximately 100 oz/ton, makes lead cake a potentially valuable product.

Bismuth is nearly always found in nature in the metallic state; but occasionally it is met with as sulphide in bismuthine and as carbonate in bismutite. It is also found in some comparatively rare minerals, such as tetradymite, combined with tellurium, and associated with gold. In minute quantities it is widely distributed: it is a common constituent of most copper ores; hence it finds its way
