Description

Technical Field

[0001] The present application belongs to the technical field of crushing and heavy medium separation in ore dressing plants, and specifically relates to an integrated processing system for fine-grained ore preparation and heavy medium separation. Background Art

[0002] Currently, many open-pit, non-magnetic mines have relatively high-grade ore. Crushing the ore to fine particles less than 10mm using heavy media separation can effectively enrich the valuable elements, thus meeting the requirements of subsequent sorting or smelting. For some minerals, heavy media separation can produce tailings with a yield of 70%-90%, significantly reducing the amount of ore to be processed later and achieving significant benefits.

[0003] Generally, raw ore must be crushed coarsely, intermediately, and finally finely to achieve a product particle size of less than 10mm. Currently, open-pit mines often use a toothed roller crusher for coarse crushing, while cone crushers are typically used for secondary and fine crushing. Existing processing plants are typically built in a fixed location, which is expensive. Furthermore, the mining areas of open-pit mines typically change year after year. While equipment is fixed within the plant, the constant shift in mining areas necessitates the use of vehicles or belts to transport the ore, increasing production costs. Summary of the Invention
