矿物颗粒在选矿设备中的运动具有一定的随机性。对于单一选矿设备中所出现的某些随机过程,如浮选槽中矿粒的相间转移,跳汰机中矿粒的分层,筛分机中矿粒的运动,苏联和西德的学者曾把它们视为马尔柯夫过程,并导出了相应的数学模型。对于串联的选矿设备,也曾有人进行过研究,但所建立的模型尚未与生产过程相联系,因而缺乏对生产的指导意义。 Mineral particles in the mineral processing equipment movement has a certain degree of randomness. For some random processes occurring in a single beneficiation plant, such as the phase transfer of minerals in the flotation cell, the delamination of particles in the jig, and the movement of minerals in the sifter, the Soviet Union and West Germany scholars They are treated as Markov processes, and the corresponding mathematical models are derived. For tandem mineral processing equipment, some people have conducted research, but the established model has not been linked with the production process, and therefore lacks the guiding significance for production.
