the process of extracting metals from their ores is called metallurgy.. the ores are generally contaminated with earthly or undesired materials (impurities). these are called gangue or matrix.. the process of metallurgy depends upon the nature of the ore and the impurities present in it.. s ome common steps involved in the metallurgical operations are : 1) crushing and grinding of the ore
alternative processing routes must be investigated. blasting the first stage of the crushing/grinding process in a production facility begins with blasting of the ore body, where the blasted material is composed of a very wide range of sizes.
under consideration is the influence of various crushing techniques on the particle-size distribution and selectivity of dissociation of basic mineral components in the composition of dalnegorsk complex ore under pretreatment. distribution of basic elements per size grades is determined in crushing feed and in products of magnetic separation and flotation.
