Biomining of metals: how to access and exploit natural

As accessible primary metal ores become lower grade, the recycling of mine wastes becomes more viable and economically appealing. It can be controlled by chemical treatments such as the use of calcium oxide that neutralizes the acid pH. The leachate metals are then precipitated in a second step using a bioreactor in which the hydrogen
