锰矿石的洗矿和选矿所形成的矿泥是锰金属损失的主要根源,一般约占总金属损失量的25～30％。所谓矿泥就是粒度为-0.5毫米的物料,其中含有-0.02毫米占50～60％,而其-0.005毫米的粒度占35～40％。矿泥的颗粒状部分(大于0.02毫米,用浮选法选别,而泥质部分(小于0.02毫米)舍弃,锰损失达10～12％。颗粒状矿泥浮选工艺的改进,细粒状矿泥的再处理,是当前提高精矿质量和金属回收率的迫切任务。
Manganese ore washing and beneficiation is the formation of sludge is the main source of manganese metal loss, generally about the total metal loss of 25 to 30%. The so-called slime is the material with a particle size of -0.5 mm, which contains - 0.02 mm to 50 to 60%, and the particle size of -0.005 mm to 35 to 40%. Particulate fractions (greater than 0.02 mm, flotated by flotation and rejected by muddy fractions (less than 0.02 mm) have manganese losses of 10-12%.) Improvements in flotation of granular slime, fine-grained ore The reprocessing of mud is an urgent task for improving the quality of concentrate and metal recovery.
