浪田坝选厂自投产以来,长期存在+74微米及-10微米粒级损失金属最多的问题,尤以-10微米粒级更为突出。今年我们在小型试验的基础上,用硫酸铵作为调整剂进行工业试验,通过22个班,处理矿石为7088吨的生产试验,铜的回收率提高5％,精矿品位提高2％,收到较为满意的效果。 (一) 矿石性质汤丹矿铜矿石氧化率较高,以今年一、二月份为例,氧化率约为72％左右。硫
Longda dam processing plant has been put into operation since the existence of +74 micron and -10 micron long-range loss of metal particles most problems, especially in the -10 micron particle size is more prominent. This year, we conducted industrial tests using ammonium sulfate as a regulator on a small scale basis. Through 22 production lines with 7088 tons of ore processed, copper recovery increased by 5% and concentrate grade by 2% More satisfied with the results. (A) Ore Nature Tangdan ore copper ore oxidation rate is higher, in January and February this year, for example, the oxidation rate of about 72%. sulfur
