Abstract
The invention provides a fluid mud agent, which comprises the following components in parts by weight: 2.5-3 kerosene, 1 kerosene emulsifier and 15-20 water. The invention further discloses a technology using the fluid mud agent to remove the mud in potassium mineral, which comprises that a cyclone separator is firstly adopted to make the mud content in the mud-contained potassium mineral reach 5-15%, and then the fluid mud agent of the invention is then used to further remove the residual mud. The fluid mud agent and the mud removing technology has good mud removing effect on high mud-contained potassium mineral, can reduce the mud content to about 2%, reduce the influence of the mud on the subsequent production, and improve the yield of potassium ion while greatly reduce the usage of sylvite collecting agent.
Description
Technical field
The present invention relates to flotation agent, specifically be a kind of fluid mud agent and contain mud potassium ore deposit desilt technology.
Background technology
China is a sylvite consumption big country; But be the very deficient country of a potassium resource, along with developing rapidly of China's sylvite industry, exhaustive exploitation so that salt lake contain mud potassium ore deposit cumulative year after year; The problem that high-grade potassium ore deposit constantly reduces causes mineral selecting and purchasing process more and more difficult.At present, at mainly the distribute Cha Er sweat Ma Haiyanhu on one of ground of China's sylvite, high-grade potassium ore deposit (potassium chloride 15%) is exhausted basically, the substitute is grade low, contain the high lean ore of mud, bad ore deposit.This type lean ore not only grade low (potassium chloride＜8%), contain mud height (cement content is at 30-60%); And raw ore constitutes complicated; Therefore, the mud in the effective elimination potassium ore deposit how, fully developing the low-grade mud potassium ore deposit that contains has become problem demanding prompt solution in the potassium resource process.
The domestic method that in the metal ore dressing, is applied to flocculation desliming and flotation desliming; As: document " application of polyvinyl alcohol in the lattice clothing spreads the copper ore floatation desliming " report; Cupric oxide ore is milled in advance-74 μ m; Carry out the flotation desliming with polyvinyl alcohol again, obtain good desliming effect, but domestic mud scum medicament about sylvite does not also appear in the newspapers.At present, domestic main employing inhibitor of mud sylvite and mechanical grading dual mode press down mud, desliming is handled for containing.Wherein, inhibitor only is suitable for the potassium ore deposit of clay content lower (less than 2%); A large amount of potassium elements are not only lost in the screening desliming, and oversize has higher clay content toward contact.
Abroad the mud scum medicament for sylvite has certain report; As patent SU810286 be with the copolymer of dimethylamine EMA and vinylacetate and iodomethane the compound after quaternized as the sludge collecting agent; But this collecting agent needs to consume a large amount of catalyst in building-up process, produces accessory substance simultaneously; Patent SU1204264 is with Epamine:75-89%, polyelectrolyte VPk-101:1-5%, the synthetic collecting agent flotation sylvite sludge that contains ethyoxyl of TRI ETHYLENE GLYCOL: 10-20%; Its effect is significantly improved, but this collecting agent building-up process to temperature, pH, and consersion unit strict demand is all arranged; Patent SU1220695 uses two (α-ethoxy)-2-alkyl miaow salt of dichloro N-of dialkyl group phosphoric acid polyethylene glycol ester and 65-90% of 10-35% with as the sludge collecting agent; To clay content is that the sylvite raw ore of 4.6-5.3% carries out the desliming flotation, and the desilt rate can reach 57.6%; Patent SU1168290 the modification of wood pulp byproduct after as the sludge collecting agent, use polyacrylamide and ethyoxyl alkyl phenolic ester simultaneously, the desilt rate is the highest can be to 68.8%, but also can lose 4.68% potassium chloride simultaneously; Lauxite is clay dispersion patent US2006226051 uses modification in saturated brine after, thereby reduced the influence of clay to the sylvite flotation, and this medicament is with the clay emersion, but clay can enrichment in tail salt, and the recycling of tail salt is caused adverse effect; Patent WO2008152029 uses ethoxylated fatty amine as the sludge collecting agent, and this fatty amine degree of polymerization is that 15-100 has a kind of alkyl group that to contain two carbon chain lengths be 1-22 of two kinds of various structure, contains the sH of characteristic group-(EO) in the another kind of structure.
According to document " high clay potassium ore flotation desliming technology perfect ", Russian Ural potassium company has obtained best floatation indicators with the collecting agent of hydroxyethylation amine as slime flotation with the hydroxyethylation amine that contains 30 ethylene oxide groups.
Though abroad the research for sylvite sludge collecting agent has comparatively mature technique with application; But because the characteristics in external potassium ore deposit are water-fast clay-carbonate impurity; And illite, chlorite, montmorillonite, kaolin are the main body composition in the sludge in the domestic potassium ore deposit; Therefore above technology is difficult to directly use in China, and research is fit to the flotation desliming operation of China's ore characteristics, just seems very important.
Summary of the invention
The object of the present invention is to provide a kind of fluid mud agent and contain mud potassium ore deposit desilt technology, this fluid mud agent and desilt technology contain mud potassium ore deposit to height and have good desilt effect.
A kind of fluid mud agent provided by the invention, meter by weight: kerosene 2.5-3, kerosene emulsifying agent 1, water 15-20;
The preparation method of said fluid mud agent comprises that step is following:
(1) in proportion kerosene is added in the container, add the kerosene emulsifying agent under the stirring state again, stir into uniform clear solution;
(2) under stirring condition, slowly water is added in step (1) the gained clear solution, when addition reaches the 20-25% of Total Water, stop to add water, keep stirring 10-30min;
(3) surplus water is continued to be added in the solution of step (2) gained, stirring is fluid mud agent.
Described kerosene emulsifying agent can use the moon/nonionic surface active agent to substitute.Described nonionic surface active agent is polyglycerol fatty acid glyceride, isomery ether or fatty acid ethoxy ester etc.
A kind of mud potassium ore deposit desilt technology that contains provided by the invention comprises that step is following:
(1) mineral powder is broken to the 60-120 order, sludge and salt crystal in the ore are fully dissociated;
(2) use cyclone separator, carry out the eddy flow desilt, make its sludge content reach 5-15%;
(3) use flotation unit; By weight 1: 3-4 adds the 10-20g polyacrylamide with stirring in the above-mentioned desliming ore deposit adding KCl-NaCl-MgCl2 saturated solution by desliming per ton ore deposit, stirs; Add the above-mentioned fluid mud agent of 4-20kg by sludge per ton again; Ventilation, flotation desliming 5-10min reduces to about 2% cement content continuously.
Compared with prior art, the invention has the advantages that:
1, through eddy flow and flotation height is contained mud potassium ore deposit and carry out the desliming processing, can clay content be reduced to about 2%, improved desliming efficient greatly.
2, the kerosene emulsion activation capacity in the fluid mud agent is strong, selectivity is high, can save the kerosene more than 5%, remarkable in economical benefits.
3, the fluid mud agent compound method is convenient and swift, and the process for preparation no coupling product generates, non-environmental-pollution.This fluid mud agent stable in properties leaves standstill not stratified for a long time.
