High-efficiency and energy-saving manganese washing process without arranging tailing pond or polluting environment

Abstract

The invention discloses a high-efficiency and energy-saving manganese washing process without arranging a tailing pond and polluting the environment. The mined manganese slime is broken by a manganese slime breaking machine and then is washed by a manganese slime manganese-washing machine to obtain manganese ore, the water for washing the manganese slime enters a tailing slime water collecting tank and separated through a tailing treatment machine, the clean water is reused and the slime is back filled. The invention has the advantages that: firstly, the manganese washing is locally carried out after mining the manganese ore, therefore, the link of manganese ore slime transport is reduced and the production and transportation cost is reduced; secondly, water resources are saved and the pollution to the environment is also avoided due to the recycling of the manganese washing water; thirdly, no tailing pond is required, not only the land occupation is little, but also the original potential safety hazard of production of the tailing pond is overcome and the construction investment is reduced; and fourthly, the manganese slime breaking machine is additionally arranged, therefore, the problem that the large manganese slime cannot enter the machine before or the damage to the manganese washing machine is great is solved, and the ore washing efficiency is greatly improved by 35 percent than the original process efficiency.

Description

technical field [0001] The invention relates to manganese ore production, in particular to a high-efficiency and energy-saving manganese washing process that does not require tailing ponds, is environmentally friendly, and has no environmental pollution. Background technique [0002] The existing manganese ore production process is: (1) mining of manganese ore source slime; (2) loading and transporting the mined slime to the manganese washing site; And manually send the manganese mud into the manganese mud washing machine with a water gun to produce manganese products; (4) The remaining tailings mud water after manganese washing needs to be pumped into the tailings pond with a sand pump or directly into the tailings pond. The disadvantages of this process are: (1) the production water consumption is large, the manganese washing wastewater cannot be recycled, the waste of water resources is large, and the environment is polluted; (2) the tailings pond needs to be set up, whic...

Problems solved by technology

The disadvantages of this process are: (1) the production water consumption is large, the manganese washing wastewater cannot be recycled, the waste of water resources is large, and the environment is polluted; (2) the tailings pond needs to be set up, which not only occupies land, but also requires a large investment and high production costs. , and tailings ponds are likely to cause dam breaks during the spring rainy season, and there are great hidden dangers in production safety; (3) The mining and backfilling transportation volume is large, labor-intensive, time-consuming and expensive; (4) The efficiency of manganese washing is low
