Process description Figure 2 shows a flow diagram of the first stage leach process The matte from the mineral processing plants is fed with demineralized water to the ball mill to increase the surface area of the particles for leaching Tank TK2100 serves as a buffer tank for the milling operation and the feed tank to the first stage circuit.
10 07 2017 Depending on the desired metal and its original matrix different solvents can be used in the leaching process these solvents are known as lixiviants For those of you unfamiliar to the term lixiviate means to leach or dissolve out The lixiviant is what leaches the metals out of the original matrix lixiviants can be acidic or basic.
