Simao Mountains And Rivers Of Zinc Oxide Ore Beneficiation Of New Technologies

Zinc have many special properties, except for comprehensive used to manufacture alloy material, It is also comprehensive used for machine manufacturing, printing, national defence and others industry,It is have more comprehensive use in modern industrial engineering, and have important status in national econamy developing.As known,the zinc ore total reserves, considerable zinc oxidized ore occupy equivalent proportion. Due to zinc sulfide ore ' end-to-end exploitation and farther drain, mineral processing industry is faced with new difficulty, Zinc oxide ore resource relatively exuberance How to dispose lead zinc oxid ore, and how to improve mineral separation indices, increase economic benefit, more and more evoke people 'attention. It si become a important problem of mineral industal and scientific research.This article perpetrate the ore deposit genesis , characteristic and others aspect clearly ,compendious introduce Analyses and compare with both here and abroad zinc oxide ore mineral separation ' s means , craft and investigation dynamic..This article aim si mao zinc oxide ore' s property,the ore oxidation degree of Zinc oxide is very deep, Craft mineralogy investigation demonstration: zinc ore ingredient complexity, mostly with smithsonite and hemimorphite 'form output, other zinc ore thing none but only 3.8%. Zinc oxidation attain 99% , Slugging severity, the ore texture loosen, frangibility, easy bring secondary slime forth This zinc ores hard to separate,but Consider of its actual conditions, comparekinds of the rejection flow scheme known as: (1) Gravity Concentration (Shakin table) ; (2 ) Flotation ; (3 ) combined process of gravity separation plus flotation , And pay attention to investigation flotation process, Search floatative new technology, new reagents.The test showed:Although Gravity Concentration acquirability out zinc concentration zinciferous for 30.61%, zincoid recovery only 17.08%; this scheme inadvisability. combined process of gravity separation plus flotation, Either both discriminability derive gravity concentration zinc concentrate and floatation zinc concentrate, thereof grade exceed or approach 30%, two kinds of zinc concentration's recovery only 78.13%, Therefor flowcomplexity, process of production hard back out.Floatation circuit structure simplicity, handiness, performances would as well, through the use of the kzf , a new sort of zinc oxide ore floatation medicament zinc,It exhibit great collectivity in the floatation test of zinc ore ,It's useful to zinc oxide ore.The zinc concentration grade for 29.50%,zinc mental recovery 88.76%.
