A single particle in the form of a certain mineral is called a monomer. Massive ores containing valuable minerals in both, and containing gangue minerals, mineral processing plants commonly used method of grinding the ore is crushed so as to most of the valuable minerals from gangue from solution, dissociation is called a monomer composition The various minerals of the ore are separated from each other. Where L is the monomer dissociation degree of a mineral, %; HUZHOU JIHAO NONWOVENS FABRIC CO.,LTD , https://www.jihaononwovens.com
Among the crushed ores, some of the particles contain only one useful mineral. These particles are called monomer dissociated particles; others are two or more minerals (including those associated with gangue minerals). Liansheng granules or continuous organisms. The monomer dissociation degree of a mineral is the ratio of the number of monomer dissociated particles of the mineral to the total number of particles of the mineral (including the number of dissociated particles of the monomer and the number of particles of the mineral in the continuous body). The percentage is expressed. 
n - the number of monomer dissociated particles of the mineral;
N - the total number of particles of the mineral;
P - the number of particles of this mineral converted by volume in the living body.
The number of monomer dissociated particles of a mineral and the number of ore mineral particles and the number of particles of the continuum (according to the volume content of the mineral can be divided into 1/4, 1/2, 3/4, etc.) can be observed under a binocular microscope And statistics. Monomer dissociation is a measure of the extent to which a useful mineral particle monomer dissociates.
