Heap leaching is a method in which a leaching solution is sprayed with a spray leaching system to selectively leach the useful minerals in the ore and recover the useful mineral from the pregnant liquid flowing out of the heap during the infiltration process. Lowgrade gold ore heap leaching is a new gold extraction process developed in the 1980s.
Vats and Column Leach. In traditional cyanide leaching, ore is placed in vats or columns. The cyanide solution percolates through the ore and dissolves the gold, which is then removed from the lixiviant by adsorption onto carbon or resins. Grain size, oxygen and alkalinity levels are carefully controlled to ensure maximum gold recovery. Heap
In the carboninpulp process adsorption occurs after the leaching cascade section of the plant, and in the carboninleach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank.
An effectively new technology of extracting vanadium from stone coals by high concentration sulfuric acid was researched. The effect of the concentration of sulfuric acid, leaching temperature, leaching time and helper leaching agent on the extraction of vanadium was explored.
