Environmental Effects of Extracting and Using Mineral Resources The scale and level of requirement of minerals have increased manifold in our country and it is heading towards the stage where much larger consumption of minerals will be inevitable to sustain even the minimum growth rate of
Mineral processing techniques are performed in environments which contain a significant amount of water, and in many cases, the most of water is removed with tailings. Therefore, it is necessary to use dewatering equipments such as thickeners in order to avoid environment contamination and water recycling Burger et al. 1999.

Our metal and miningprises of over 3100 mines D R Khullar. In 2010, the costs of these mines were estimated $106.4bn 㿰.5bn.
The USGS United States Geological Surveymodity Survey for 2015 lists more than 90 different minerals from abrasives to zirconium. Of these, 14 have a U.S. mine production of more than $1 billion in 2014. Extracting useful minerals is an arduous and technically demanding process. First, any material on top of the deposit, known as overburden, must be removed or tunneled through

If the subsequent operation is mineral processing based on physical properties/surface properties I feel blending does not serve any purpose .When these particles enter the process, each particle is on its own and would respond according to its size/shape/specific gravity/surface property. It does not look for its partner with whom we did blending to get an average. I think https://www
