Depletion of high grade resources has necessitated the use of low grade fines, which contain good amount of mineral values and also liberate in finer sizes Froth flotation, a physico chemical surface based process, is the most established solution, both technologically and economically, compared to other alternatives for fines beneficiation

The role of mineral processing in reducing the environmental impact of mining activity The mining activity is destructive in our environment and can cause bad effect in our health but it is an important industry and it is a major in the global economic development and growth

These challenges provide opportunities for the application of mineral processing and extractive metallurgical principles to add value to wastes/co products, reduce energy consumption and recycle complex and novel materials This paper discusses the interpretations of sustainability and relates them to the minerals industry

Dewatering is an important process in mineral processing The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue

Minerals in the Earth's Crust There are more than 3000 known minerals the number is still growing, but of these only about 20 are very common, and only 9 of these constitute 95 of the crust These 9 minerals are all silicates, and are also called the rock forming minerals They can be subdivided into two groups, the mafic and felsic minerals according to the principal rocks types they mainly

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry

Mineral processing wastes are available from mining and mineral processing operations, most of which are located near the mine source and operated by mining companies The quality of mineral processing wastes can vary widely and is highly dependent on the specific source
