Theoretical-probability approach to analyse the iron ore grinding process

Abstract

Iron ore mining and pro cessing rank very high in the economy and industry of Ukraine. About 20% of the world's iron ore resources are on the territory of Ukraine and the annual production of iron ore materials in Kryvbas surpasses 60 million tons The key reason that affects the quality of the concentrate outputs at the concentrating factories is the stochasticity of the iron ore properties supplied to the primary grinding. Among the significant properties of iron ore can be defined hardness and iron content. The wide variations in the properties of iron ore at the primary grinding affect the subsequent stages of ore processing and the quality of the concentrate. Therefore, the stability of the concentrate quality is required, which is principal in the heat of competition. Thus scientific research and practical implementation in this scope are especially relevant in the current conditions of the concentrating factories.
