Environmental Impacts and Health Aspects in the Mining Industry. 12. Impacts on the Biosphere The biosphere is adversely affected by mining mainly by pollution and by degradation of land and vegetation resulting in loss in biodiversity. Mining can also have impact on local microclimate (Aswathanaryana 2003).
PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the postclosure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. Exploration

Mineral processing. Written By: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Thus it can be expected that the environmental impacts, particularly energy consumption and greenhouse gas emissions, of mining and mineral processing for many metals will become much more significant in the future than they currently are.

Mineral processing. Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.
Mining facilities such as offices, shops, and mills, which occupy a small part of the disturbed area, are usually salvaged or demolished when the mine is closed. The open pits and waste rock disposal areas are the principal visual and aesthetic impacts of mining.
The processing of mineral monazite to produce thorium (Th) and rare earth elements may create a radiological impact if the processing and residue are not properly or safely managed. Malaysian Atomic Energy Licensing Board (AELB) categorized monazite as a radioactive material because the concentration of thorium in the mineral is higher than 1Bq/g.
