Study on optimization of secondary recovery technology for low-grade stocked ores in an antimony mine
In response to a situation where a number of ores in a mining stope of a certain mine were not promptly released due to production reasons,leading to the long-term accumulation of ores in the stope and the oxidation and agglomeration of some ores,making it difficult to recover the ore smoothly,this study,based on the actual situation of the mine,describes the recovery methods for this part of ores based on the classification of the ores in the storage stopes.The footwall unit grid method,was proposed for the recovery of dense oxidized and cemented ores,which achieved good economic results.
