The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent2 天前2 pH is important for pyrite flotation Normally, pyrite can float well at acid conditions without adding any activator However, if you want to float the pyrite at alkaline conditions, you need to add Cu2+ as activator, because pyrite can be depressed at alkaline conditions 3Froth Flotation (Sulphide & Oxide) Metallurgist
Fundamental electrochemical studies of sulfide mineral
Froth flotation is a widely used, inexpensive process for commercial separation of minerals from gangue and minerals from each other Extensive research has demonstrated that electrochemistry governs the flotation of sulfide minerals Flotation often is adversely affected by uncontrolled oxidation, which also is an electrochemical processFroth flotation represents the most versatile separation method in mineral processing It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zincFroth flotation: a quick overview European Training
Froth Flotation Process Used in the Lead Zinc Sulfide Ore
The leadzinc sulfide is often associated with a variety of valuable components, such as lead, zinc, copper, sulfur and other useful minerals, whose floatability is obviously different, which determines the different froth flotation process of lead and zinc sulfide ores The common froth flotation process of sulfide ore mainly includes priorityThe content of the coarsegrained monomer must be less than the upper limit of the particle size of the mineral flotation At present, the upper limit of flotation particle size is generally 02503 mm for sulfide minerals; 051 mm7 Factors Affecting Froth Flotation Process
