Quantification of water usage at a South African platinum processing plant
Platinum ore is transported from the mine to the processing plant by conveyor, road or rail. The ore is processed by crushing and milling to reduce the coarse ore to fine particles, liberating the sulphide-containing platinum group metals (PGM), iron, nickel and copper from the waste ore. This allows for easy separation during flotation ...
Soil Phytomining: Recent Developments—A Review
Phytomining (PM) is defined as the process of using plants capable of bio-extracting metals from soil in order to explore them economically. This relatively new, innovative method has been gathering significant attention in both the academic and commercial domains. Conventional mining methods are often economically unviable when applied to lean ores, and they can lead …

Evaluating the environmental and economic impact of mining for …
On the other hand, large-scale mining mostly underground mining uses explosives for blasting to pave the way for the mineral ore of interest. The effect of blasting is that it causes a breakdown of the soil profile (soil structure and texture), affecting the soil water holding capacity due to the substantial level of ground vibration ( Mensah ...
Types of Placer Wash Plants
The floater plant, also known as a "Doodlebug" is a very efficient way to mine. The plant can be mounted on pontoons or a barge. Floater plants have the ability to move very rapidly in a pond of their own making. It takes planning to operate efficiently without boxing yourself in but when properly executed a floater setup can move a lot of ...
Fossil Energy and Carbon Management
In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. A form of surface mining, mountaintop mining, is where the tops of mountains are removed, allowing for almost complete recovery of coal seams. Underground (deep) mining is used when the coal is more than 200 feet below the surface.

Rare earths are used in the renewable energy technologies such as wind turbines, batteries, catalysts and electric cars. Current mining, processing and sustainability aspects have been described in this paper. Rare earth …
Integrating renewable energy in post-mining land uses
Using the random sample method, we found a range of post-mining land uses, but did not identify renewable energy as a common land use. In the literature review (below), we describe one example of a renewable energy facility on a decommissioned mine site in British Columbia. International Post-Mining Land Uses from Literature Review

How Metal-Absorbing Plants Could Make Mining Greener
Scientists are exploring a somewhat unusual green energy solution: mining metals from the earth using plants. Typically, if soil has high levels of metal, plants will either die or do everything they can to avoid it. But, one group has taken a different path: evolve to be able to safely absorb large amounts of the metals. These special plants ...
