Description

A kind of combination medicament and its application method for zinc-containing ores flotation
Technical field
The present invention relates to a kind of combination medicaments and its application method for zinc-containing ores flotation, belong to mineral floating medicament Field.
Background technique
Zinc is the important strategic nonferrous metal resource of country, and copper and aluminium, zinc energy are only second in the consumption of non-ferrous metal The more excellent alloy of physical and chemical properties is made with various metals, it has comprehensive important work to the national economic development With.It is shown according to the data that US Geological Survey counts, the zinc reserves that the world is verified are 1.8 hundred million tons, and zinc proved reserves are more than There are Australia, China, Peru, Kazakhstan and the U.S. in 10000000 tons of country, the zinc resource storage that these countries are verified Amount almost accounts for the sixty percent of global zinc resource reserves.China's zinc ore reserves account for the 18.3% of the skilful reserves in the world, account for the world and possess The 19.2% of reserves occupies second place of the world, therefore the development and utilization of China's zinc resource has important role in the whole world.
The zinc metal reserves of zinc oxide ore have been verified at 80,000,000 tons or more by China, are concentrated mainly on Yunnan, Guangxi, the Liao Dynasty Rather, the ground such as Gansu, Qinghai and Inner Mongol.Usual lead and zinc association form lead-zinc deposit, Yunnan Pb-Zn deposits resource reserve 2764.86 It ten thousand tons, ranks first in the country, also occupies the forefront in the world, at home and abroad there is in Mineral Market bigger advantage.It mainly divides Cloth is in three " three rivers " area county Lan Ping, South-east of Yunnan and Northeast Yunnan, China areas.Blue level ground Jinding Lead-zinc Ore category oversized mineral deposit, verifies lead 1574.61 ten thousand tons of zinc reserves, big mineral zone 7;In addition there are all imperial tin zinc ores in Maguan, Gejiu tin symbiosis Pb-Zn deposits, Huize Pb-Zn deposits etc..Yunnan Pb-Zn deposits have deposit type complete, rich reserves, put more distributions wide, reserves Relatively centralized and grade Relatively leaner and have for characteristics such as the beneficial elements of comprehensive utilization, mineral deposit Zn content is greater than lead(Pb:Zn=1:2.5~3), mineral deposit In except altogether(Companion)Raw silver is outer, is often associated with the elements such as gold, copper, tin, germanium, cadmium, thallium.
So far, grown up recycle zinc dressing method it is very much, mainly have floatation, there are also gravity separation method, weight Choosing-flotation combined process, flotation-hydrometallurgy combined process flow, gravity treatment-hydrometallurgy process, roasting-flotation combined process and selectivity Flocfloatation etc..In this numerous method, due to various, floatation is mainly used.Currently, recycling zinc Floatation process be diffeential floatation method, i.e., the sulphide ore easily selected is first selected, then select the technique of oxide ore, the main reason is that ore can Buoyancy differs greatly, it is difficult to find suitable medicament and sulphide ore and oxide ore are carried out while being recycled.
Summary of the invention
The present invention provides a kind of combination for zinc-containing ores flotation for deficiency existing for existing zinc-containing ores flotation Medicament is not needed sulphide ore and oxide ore separating flotation using the medicament, can be realized simultaneously zinc sulfide ore and zinc oxide ore Flotation, flotation efficiency is high, and, down cloth granularity thinner zinc-containing ores higher particularly with clay content have preferable collecting effect The grade and the rate of recovery of zinc concentrate can be improved in fruit.
To achieve the goals above, the invention is realized by the following technical scheme:
A kind of combination medicament for zinc-containing ores flotation, each raw material and its mass percent are in the combination medicament:Different hydroxyl oxime 5 ~ 40wt% of acid, 10 ~ 50wt% of ethylenediamine, 10 ~ 60wt% of xanthate, 5 ~ 40wt% of palmityl glycine.
The carbon chain lengths of hydroxamic acid of the present invention are C6~C8, the carbon chain lengths of xanthate are C2~C5
The method that combination medicament of the present invention is used for Flotation Recovery Zinc, specially:First by zinc-containing ores raw ore ore grinding to- 0.074mm accounts for 50% ~ 95%, then adds pH regulator sodium carbonate 200g/t ~ 1500 g/t, gangue inhibitor calgon The g/t of 500g/t ~ 2000 finally adds combination medicament 20g/t ~ 300 g/t.
Beneficial effects of the present invention:
(1)Combination medicament used in the present invention is hydroxamic acid, ethylenediamine, xanthate and palmityl glycine, is all conventional medicine Agent is easy to get, cheap, and these types of medicament is mixed according to a certain percentage, and the interaction between medicament contains in flotation Flotation effect is improved by synergistic effect when zinc ore;Meanwhile collecting ability can be remarkably reinforced for independent addition, Reach raising floatation indicators, reduce the consumption of medicament, reduces the effect of production cost.
(2)When using combination medicament flotation zinc-containing ores of the present invention, zinc sulphide and zinc oxide can be carried out same Shi Huishou does not need substep and carries out flotation, simple process, it is easy to accomplish.
(3)The zinc-containing ores that the combination medicament is high to clay content, grade is low, ore properties are complicated are imitated with preferable collecting Fruit, selectivity is strong, and production cost is low.
