Technology of extraction of rare earth metals
Finnish mobile equipment for the extraction of rare earth metals - gold, platinum, silver and other
Large processing plants operate with a capacity of 65-85% on average, so that over the years there accumulated a huge amount of once processed ore with a certain content of precious metals, on average, 15-35% of the original content of precious metal.
The low content of precious metal in the ore does not allow the plants to reprocess their waste and extract the rest of precious metal content after the first treatment. Re-processing cost is higher than the cost of recoverable precious metal. The waste accumulated over the years since the contence of, for example, mercury or parts of cyanide doen’t allow to realize the spent ore for any purpose. Waste of such plants - is an environmental problem.
Application of technology
The Finnish company Inno Technologies Oy has developed a technology and a mobile unit, which has a high mobility and productivity. The unit is an Offshore Container of 40 feet, which can be moved to the territory of mining and processing complex, and perform the following functions:
Extraction of gold, platinum or any other rare-earth metals from alluvial deposits of sand, crushed ore indigenous materials and technogenic dumps of processing plants.
Cleansing of contaminated soil from heavy metals.
The work is performed by the Finnish Company Inno Minerals Oy
