Methods of oxidative ammonia-sulfate leaching of natural raw materials of complex composition are widely used in industry [6-7].
In this case, the general model of cascade consists of three models of reactors arranged in series and connected by material flows of reagents.
The model of each reactor consists of blocks of chemical kinetics, hydrodynamics, and material balances.

In previous study for failure mechanism of fractured rock, there is a laboratory experiment method where uses rock specimens or real rock material made of joints and fissures to research the mechanical properties of fractured rock in condition of simple fracture distribution.
At present, for research of fractured rock mechanics properties at home and abroad, many scholars [1~8] made a lot of achievements, such as from continuum model, discontinuum model to semicontinuum model [1~3]; from uniform material mechanics to non-uniform material mechanics; even from macro material to micro material to study failure mechanism of fractured rock [4,9].
It is assumed that the mechanical properties of whole element material obey Weibull distribution.
