pollution from mineral processing of ore

Sources of pollution: metals and mineral processing

The main processing phases are separation of valuable minerals from unwanted minerals, recovery of valuable minerals from the ore, and metals production and refining. Most of the emissions from processing are to air, but some are also to water and land. Canada’s provinces have primary jurisdiction over metals and mineral processing.

Mineral Resources: Formation, Mining, Environmental Impact

Processing metallic ore (e.g., gold, silver, iron, copper, zinc, nickel, and lead) can involve numerous steps including crushing, grinding with water, physically separating the ore minerals from non-ore minerals often by density, and chemically separating the metal from the ore minerals using methods such as smelting (heating the ore minerals

Pollution from Mining

Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.

Environmental Effects of Extraction Mineral Resources

Water pollution is a common feature of mining and associated mineral processing activities. Erosion of external overburden dumps during heavy rains is a major water pollution problem in mining areas. Abandoned mines and the disposal of chemicals used in refining are significant sources of water pollution in mining areas.

Mining and Water Pollution — Safe Drinking Water Foundation

Dec 17, 2016· 3. Processing Chemicals Pollution This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4. Erosion and Sedimentation

Mineral Processing an overview ScienceDirect Topics

The sources of air pollution are mine production (drilling and blasting, particularly in open pit mines) (Fig. 14.6), mineral processing plants (crushing and grinding), ore and waste handling, workshops, and large numbers of transport vehicles (Fig. 14.7). Air pollution causes injury to eyes, throat, and the breathing passage and lungs of

Environmental Risks of Mining

This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological

Environmental impact of mining Wikipedia

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of
