Improvement of pretreatment and extraction technologies for contrast ore in mining structurally complex deposits

The data on ore pre-concentration in the course of processing with separation are analyzed. The analytical and technological studies into lead-and-zinc ore samples from a deposit located in Russia’s Far East, with the determined yield of size grades and material constitution are presented. The authors propose an improved technology for the pretreatment and extraction of contrast nonferrous metal ore from structurally complex despots. The technology enables the increase in the end-to-end extraction of metals owing to individual processing of high-grade and low-grade fractions of ore using dedicated flow charts including flotation as well as heap and in situ leaching. High content of useful components in the concentrate of size-based separation of high-grade ore allows using special processing techniques which ensure high level of extraction at relatively low cost of the end product. In case of joint processing of ore fractions having essentially different strength properties, it is proposed to subject them to separate crushing and milling to reduce formation of slime particles and aggregates, with the subsequent mixing and blending into a pulp in order to decrease the loss of useful components during flotation. The comparative technical-and-economic calculations implemented as a case-study of mining and processing of complex ore from an extraction block of the test deposit show that the use of the proposed technology enables the increase in the end-to-end metal recovery (with zinc reduction) by 4.1%.
