摘要：
In order to economically recover the copper from the low-grade copper ores, a bioleaching-solvent extraction-electrowinning plant with a design capacity of 2 000 t cathode copper per year in Dexing Copper Mine was operated in September, 1997. The results during the 10-month period of the industrial copper dump leaching have been obtained and the approaches have been carried out Co enhance the copper dissolution from the waste rocks. The overall operation flow; sheet is depicted. The problems confronted in the process and possible way for improving are discussed.
