Abstract
The invention relates to a process that raw mine is ground into powder which is added with water to be prepared into pulp. Under certain pH value, inhibitor of carboxymethylcellulose nano solution, industrial water glass and tannin solution are added proportionally for absorbing calcium, magnesium and silicate. Then, sodium oleate is added as a collector for closed circuit circulation floating. Foam products after the floatation are flushed by water and then enter a sedimentation tank for the sedimentation or the pressure filtration. Thus, manganese concentrate fines above 20 percent are obtained. In the process, floatation is implemented on low grade poor manganese mine containing 10-14 percent of manganese, carbonaceous rock with the manganese content of 4-9 percent and electrolytic manganese leached slags with the manganese content of 1-3 percent to obtain manganese ore fines, the manganese content of which reaches above 20 percent. The recovery of manganese is more than 85 percent. And non-manganese emission for tailings can be realized. The manganese resources are lead to have extremely high utilization rate. Produced products can also lower acid consumption and ammonia consumption for electrolytic manganese production of downstream industry of manganese mines.
Description
Technical field
The present invention relates to a kind of flotation method of low ore grade manganous carbonate ore.
Background technology
The manganese carbonate ore major part of China is low-grade poor manganese ore, and along with the increasing of market demand and yield, high-grade rich manganese ore is fewer and feweri, and low-grade manganese carbonate ore is carried out beneficiation enrichment, has become current ore dressing industry one big focus.In the manganese ore, Main Ingredients and Appearance is manganese carbonate, calcium carbonate, magnesium carbonate, quartz, silicate, pyrite, wherein contains manganese carbonate and is about 4-14%, and calcium carbonate and magnesium carbonate are about 10-30%, and silicate is about 20-30%, and iron is about 5%.Several main mineral generally are the mutual embedding of microfine gives birth to, and causes various mineral in the mineral deposit spatial dispersion.Between each mineral aggregate, some is more even for the composition of mineral and chemical property, and some is inhomogeneous, and the amount of institute's manganese-bearing mineral also is variation from high to low.
Mainly be to adopt the method for magnetic separation that manganese ore is carried out ore dressing at present both at home and abroad, but the enrichment degree of magnetic separation is not high, be merely able to improve about 5 grades, and the rate of recovery of manganese is also very low, most of magneticore-dressing plant can only be controlled at the rate of recovery of manganese in 40%, and not only the waste of energy consumption height but also raw ore is big.
Summary of the invention
Purpose of the present invention aims to provide a kind of enrichment degree height, flotation method of low ore grade manganous carbonate ore that the rate of recovery is high.
The present invention is ground to the 160-200 order with the raw material ore deposit, manganese carbonate is separated with other mineral, it is the ore pulp of 20-30% that breeze is added water furnishing concentration, utilize manganese carbonate and calcium carbonate, magnesium carbonate is under different PH and different medicaments, the selective difference bigger to being adsorbed with of aliphatic acid, the adding weight percent concentration is that the aqueous sodium carbonate of 10-20% is regulated the pH value of ore pulp between 7-9, original ore powder per ton then needs CMC solution, it is 5% CMC solution that water for industrial use glass and tanning solution add weight percent concentration in the ratio (weight ratio) of 1:0.0005-0.004:0.002-0.005:0.001-0.002, weight percent concentration is that the water for industrial use glass of 40-50% and weight percent concentration are that 20% tanning solution stirred 5-10 minute, adjust ore pulp, treat calcium, magnesium, after the silicate absorption fully, add the stronger enuatrol of foamability as collecting agent, it is the enuatrol of 0.75mol/L in ratio (weight ratio) the adding molar concentration of 1:0.001-0.006 that raw ore per ton needs enuatrol, enter in the flotation device then, difference according to manganese content in the raw ore is carried out the closed cycle flotation, through a primary election, 3-5 time selected after, enter the sedimentation basin precipitation or carry out press filtration after the froth pulp water flushing that floatingly selects, just can get the manganic concerntrate powder more than 20%.
Use method of the present invention, the electrolytic manganese leached mud that the low-grade poor manganese ore that contains manganese 10-14%, carbonolite that manganese content is 4-9% and manganese content are 1-3% carries out flotation, can obtain manganese content and reach rich manganese ore powder more than 22%, the rate of recovery of manganese reaches more than 85%, and the manganese content of mine tailing is extremely low, basically can reach no manganese discharging, make the manganese resource utilization high, the product of output also can be the downstream industry of manganese ore---the electrolytic manganese production process reduces acid consumption and ammonia consumption.
Specific embodiments
Embodiment: the specification of adjusting the used agitator of ore pulp is 1.2 meters of diameters, and high 1.2 meters, its dischargeable capacity is about 1 cubic metre.After adding water, the water yield is about 1 cubic metre, dropping into manganese content (weight) again is 10%, fineness is 300 kilograms of 180 purpose original ore powders, stir, make pulp density between 20%-30%, when stirring, adding weight percent concentration and be 20% aqueous sodium carbonate, to regulate the pH value of ore pulp be 8, adding weight percent concentration in the ratio (weight ratio) of 1:0.002:0.003:0.0015 then is 0.0006 kilogram of 5% CMC solution, weight percent concentration is that 0.0009 kilogram in the water for industrial use glass of 40-50% and weight percent concentration are that 20% tanning solution stirs for 0.00045 kilogram, stirred 5-10 minute, treat calcium, magnesium, after the silicate absorption fully, ratio (weight ratio) adding molar concentration in 1:0.004 is the enuatrol of 0.75mol/L, enter then and carry out the closed cycle flotation in the flotation device, through a primary election, again with the primary election product after triple cleaning, with carrying out press filtration after the froth pulp water flushing that floatingly selects, can get the manganic concerntrate powder more than 20%.
