The resource recoverying and utilizing method of manganese ore mud and equipment
Technical field
The present invention relates to the recovery and utilization technology field of mineral waste, the resource being specifically related to a kind of manganese ore mud reclaims profit
Use method and apparatus.
Background technology
Manganese is one of important foundation raw material of the national economic development, has the steel industry being related to National Industrial lifeblood
The demand of " without manganese not Cheng Gang ".Manganese and compound application thereof are extensive, from basic body trace element, feed additive to
The alloy material of new and high technology, battery material etc., its demand is increasing along with the development of society, and the utilization of manganese is to national economy
Development play important facilitation.
Existing manganese ore production procedure is: 1, the exploitation of manganese ore seedbed sludge;2, exploitation sludge entrucking is transported to washup
Place;3, washing manganese place outfit stacking manganese ore mud and washing manganese platform, and with manually manganese mud hydraulic giant being sent into manganese mud log washer, raw
Output manganese product;4, wash manganese remaining tail manganese ore muddy water and need to be pumped into or flow directly into tailings mud storehouse with sand.This technique is not
Foot is: in the manganese ore course of processing, manganese ore mud annual emissions is more than 2,000,000 tons, and in manganese ore mud, manganese content is 6-10%, utilization rate pole
Low.For a long time, comprehensive, effective utilization ways is not the most found in the process to manganese slag, substantially uses and piles up or fill out
The mode buried.Thus, the land resource amount taken increases year by year, polluted underground water source, and mineral resources waste is serious, production cost
Rise year by year.
And China be main promoter manganese state and manganese ore processing state, manganese ore reserves occupy the 7th, the world, manganese ore
Working ability also position is at the forefront in the world, but long-term existence, and lean ore is many, the contradiction of rich ore critical shortage.The explored manganese ore of China
Stone is mainly manganese carbonate and manganese oxide ore, and wherein, manganese oxide ore accounts for the 24% of gross reserves, and average manganese grade is only left 20%
The right side, in order to meet market demand, China still needs to a certain amount of rich manganese ore of import every year.Therefore, combining for poor manganese ore resource
Close evaluation and exploration technology and equipment is to solve the self-supporting key point with promotion manganese industry development of my manganese ore.
Summary of the invention
The present invention proposes resource recoverying and utilizing method and the equipment of a kind of manganese ore mud, and water content is more than by the present invention
80%, Fe content is that the manganese ore mud of 6-10% by screening, electromagnetic separation, dense, filter pressing and the operation such as press dry, and obtains water content and is less than
10%, containing the manganese ore mud that Fe content is more than 20%, make manganese resource of tailings obtain abundant, reasonably utilize, economize the land resource, carry
