The process of froth flotation entails crushing and grinding the ore to a fine size. This fine . The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and non-flowing. . The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.
The major hazards are exposure to ore dusts during ore processing and smelting, metal fumes (including zinc and lead) during refining and roasting, sulphur dioxide and carbon monoxide during most smelting operations, noise from crushing and grinding operations and from furnaces, heat stress from the furnaces and.
