effects on chemical mineral processing on the environment
Environmental Impact of Flotation Processing . Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted.
Mineral Processing is the field of extractive metallurgy also commonly known as ore dressing and involves the process of separating valuable minerals from their ores. Mineral Processing Engineers will use highly sophisticated processes and technology to extract and refine valuable metals from raw ores.
The Harmful Effects of Mining. While mining provides us with the minerals we need, it is also very destructive because it disrupts the landscape both on the surface and underground.

Aug 26, 2008· Abstract. Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process …
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 carbon which have ...
Chemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions. Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment. New or secondary minerals develop from the original minerals of the rock.
Mines and environmental impact That a mine still has some measure of impact on its environment is inevitable. The most tangible impact comes in the form of noise and dust, intrusion on the landscape, and the emission of pollutants into the air and surrounding watercourses, lakes and groundwater.
