Abstract
The invention relates to an ore dressing method for recycling scheelite from tungsten ore which is rich in arsenopyrite. The method is characterized in that: (1) the flotation of sulphide ore is performed: the tungsten ore is crushed, ground and floated so as to obtain the sulphide ore and sulphide ore flotation tailing which are mainly composed of arsenopyrite; (2) the rough flotation of scheelite is performed: the sulphide ore flotation tailing is mixed with sodium carbonate and sodium silicate, then is added with a collector, namely, sulfating nascent soap; the scheelite concentrate and the coarse ore and the scheelite coarse flotation tailing are obtained by stirring, rough flotation, fine flotation and scavenging. The method provided by the invention is characterized in that the process is simple, the beneficiation reagent has low cost, the recovery rate of tungsten is high, and scheelite concentrate and coarse ore with the recovery rate of tungsten ranging from 80 to 90 percent and containing WO3 which accounts for 4 to 10 percent is obtained.
Description
Technical field
The present invention relates to a kind of beneficiation method, particularly a kind of beneficiation method that from the tungsten ore that is rich in mispickel, reclaims scheelite.
Background technology
Mineral intergrowths such as mispickel and pyrite, scheelite, ferberite, diopside, the tremolite, garnet, fluorite, quartz, sericite, calcite.From tungsten ore, isolate mispickel and scheelite and be considered to an ore dressing difficult problem always.The existence of mispickel in the tungsten concentrate product not only influences the quality of concentrate product and follow-up metallurgical processing procedure, and also unfavorable sale price and sale bring serious environmental problem simultaneously.No matter from environmental protection, still to select aspect the smelting benefit in raising, the further investigation to tungsten ore removes mispickel all has crucial meaning.The recovery of China's association arsenic mineral at present is very limited, thus tungsten ore and mispickel separate and the comprehensive recovery of mispickel becomes the important topic of mineral process technology always.
The method that reclaims the scheelite routine has gravity separation method and oxidized paraffin wax soap floatation.Gravity separation method reclaims scheelite and is meant the method for isolating scheelite according to the difference of specific gravity of ore.The density of mispickel and scheelite is approaching, is 5.9～6.2g/cm
3The hardness of mispickel is big, Mohs' hardness 5～6.5, is difficult to levigate.Scheelite is crisp, and Mohs' hardness 4.5 is easy to levigate excessive.After ore was pulverized, the particle of mispickel was thicker, and the particle of scheelite is thinner.Therefore, reclaim scheelite with gravity separation method in this ore, separating effect is bad.Because it is very approaching with the calcic gangue minerals such as the fluorite that is rich in calcium, calcite, garnet and the surface of the scheelite performance of swimming to be rich in diopside, the tremolite of calcium, magnesium in this ore, flotation effectively separation is very difficult.The oxidized paraffin wax soap floatation be with raw ore behind broken, ore grinding, remove sulfide mineral through sulfide flotation again, its mine tailing adds sodium carbonate 500～2000 grams, waterglass 1000～8000 grams, add oxidized paraffin wax soap 300～2000 grams and make collecting agent, stirred 1～8 minute, the beneficiation method of scheelite is reclaimed in the back flotation of sizing mixing.The recovery rate in ore-dressing of the tungsten of oxidized paraffin wax soap floatation is lower.
Summary of the invention
It is good to the present invention seeks to propose a kind of sorting result, the tungsten recovery rate height, and technology is simple, and used reagent cost is low, can also reclaim the beneficiation method that reclaims scheelite from be rich in mispickel of mispickel simultaneously.
Beneficiation method of the present invention is made up of following steps according to this: 1) sulfide flotation: with the tungsten ore crushing raw ore, be milled to-0.074mm accounts for 80～85%, and flotation obtains based on sulphide ore that contains mispickel and sulfide flotation mine tailing; 2) white tungsten is roughly selected: by tungsten ore raw ore weight per ton, the sulfide flotation mine tailing restrains with sodium carbonate 1000～2000 grams, waterglass 2000～8000, the back interpolation collecting agent sulphation of sizing mixing oleic acid soap 200～1000 grams, stirred 1～8 minute, roughly select through 1 time, 2～4 times selected, scans for 2～3 times, obtains white tungsten rough concentrate and white tungsten rougher tailings.Wherein 40～80% sulphation oleic acid soap is used to roughly select, and 20～60% are used to scan.
The present invention carries out sulfide flotation earlier and reclaims to contain the sulphide ore of mispickel; It is on oxidized paraffin wax soap method basis that white tungsten is roughly selected, and the collecting agent sulphation oleic acid soap of employing has replaced oxidized paraffin wax soap, has both effectively improved white tungsten and has roughly selected index, has reduced the consumption of collecting agent again.
