The extraction of gold from combusted in boiler coal

The extraction of gold from combusted in boiler coal.

 

 

Mining gold etc non-ferrous metals from combusted in boilers of coal or lignite is carried out by filtering the smoke from the burning of coal. This technology allows you to mine gold when its concentration in the feedstock (coal) up to 1 gram per tonne.

The technology is awaiting funding!

Description:

The extraction of gold from combusted in boilers of coal or lignite is a promising direction of extraction of gold.

In the stone and brown coal of Siberia and the Far East contains gold in the range of 0.5-5.0 grams per tonne. Its extraction by conventional methods is impossible. The burning of coal, the gold is carried away with flue gases and ash in the form of volatile compounds. The same goes for other precious and non-ferrous metals.

Established technology and technological complex of production of gold and so on non-ferrous metals by filtering of the smoke from the burning of coal. In this case, the filters are deposited both beneficial and harmful components. This technology allows you to get gold when its concentration in the feedstock (coal) up to 1 gram per tonne.

The principle of operation is simple: the smoke from the burning of coal is a hundred-fold purification system. First, impurities are washed with water, then captured by the filters, and then extract gold concentrate, which is given to refining.

 


Advantages:

– extraction of gold at low concentration in the feedstock (coal) – up to 1 g/t,

high profitability. When burning 50 tons per hour of coal in a CHP, you can retrieve more than 200 kg of gold per year in its content in the initial coal to 1 g/t.
