Apr 06, 2021 Froth 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 zinc.

Aug 24, 2011 Ca (g/min cm2), the maximum solids concentrate rate or carrying capacity in column flotation, is expressed as the mass of solids from the overflow per unit of column cross sectional area. It can be measured for a given set of operating conditions by determining concentrate solids rate as a function of feed solids rate. Carrying capacity is expected to depend on particular variables, such as ...

PROBLEM STATEMENT There are two problems identified at the Mimosa Mine. They are (i) Low PGE recoveries (79% compared to the South African Merensky operations recoveries of between 80% and 95% ...
Aug 01, 2018 Talc is a naturally hydrophobic mineral, and therefore it is easily floatable. There have been many studies to overcome this problem, and depress talc with various reagents. In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase.

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.
