Description
Technical field
The invention belongs to technical field of beneficiation, and in particular to a kind of combined capturing and collecting agent raising low-grade lead zinc-silver polymetallic ore
The method of mineral processing index.
Background technique
The lead grade 0.6% or so of low-grade lead zinc-silver polymetallic ore, zinc grade 1.6% or so, silver-colored 70g/t or so are former
Mine disseminated grain size is thinner, the sulfide minerals such as association pyrite, larger to mineral processing index interference.The prior art is sorting process
In, using the single medicament such as xanthate or diethyldithiocarbamate as when collecting agent, using the single medicament such as xanthate or diethyldithiocarbamate as
When collecting agent, although concentrate grade can achieve sale substantially and require: lead concentrate leaded 50% or so, zinc concentrate are left containing zinc 40%
The right side, but xanthate have stronger subsequent collection performance but selectivity it is poor, diethyldithiocarbamate have stronger selectivity but subsequent collection performance compared with
Xanthate is poor, and the rate of recovery of each metal is lower: the rate of recovery is lead zinc 80% to 85%, and total silver 75% to 80% is difficult to improve.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of combined capturing and collecting agent raising low-grade lead zinc silver polymetallic
The method of mine mineral processing index, it is therefore an objective to by being applied in combination for two kinds of medicaments, in lead-zinc sulfide ore during sorting, sufficiently send out
Respective advantage performance is waved, has certain selectivity while strengthening collecting, both ensure that the concentrate grade of lead zinc, simultaneously
Greatly improve the rate of recovery.
Combined capturing and collecting agent of the invention improves low-grade lead zinc-silver ore-dressing of polymetallic ore and refers to calibration method, according to the following steps
It carries out:

Tailing；
(4) it is added lime into zinc rougher concentration, adjusts pH to 11.5, obtain that zinc is selected rough, and zinc is selected rough through floating
Choosing obtains zinc concentrate and zinc cleaner tailing；Copper sulphate stirring is added into zinc rougher tailings, copper sulphate additional amount is 100g/t zinc
Butyl xanthate and ethyl xanthogenate stirring is added in rougher tailings, and butyl xanthate additional amount is 20g/t zinc rougher tailings, and ethyl xanthogenate additional amount is
20g/t zinc rougher tailings is eventually adding butylamine, and butylamine additional amount is 20g/t zinc rougher tailings, obtains zinc and scans mine, zinc is scanned
Mine obtains zinc scavenger concentrate and tailing after scanning, wherein zinc scavenger concentrate and zinc cleaner tailing return to zinc roughing flotation stream jointly
Journey；
(5) silver is recycled from lead concentrate and zinc concentrate.
Silver is association in lead zinc and other sulphide ores, can only be by the recycling to sulphide ores such as lead zinc to realization pair
The recycling of silver to being separately separated for silver is realized in smelting link.But metal values of the silver in different minerals are widely different,
The rate of recovery silver-colored in lead concentrate should be improved as far as possible.
Compared with prior art, the features of the present invention and beneficial effect are:
The present invention passes through being applied in combination for two kinds of medicaments, and in lead-zinc sulfide ore during sorting, two kinds of medicaments are sufficiently sent out
Respective advantage performance is waved, has certain selectivity while strengthening collecting, both ensure that the concentrate grade of lead zinc, is recycled
Rate has also obtained certain amplitude raising.
The present invention uses diethyldithiocarbamate for main collecting agent in lead process, and butylamine black powder, 25# black powder are supplementary catching agent, zinc
Process ethyl xanthate and butyl xanthate are according to the proportion of 1:1 as main collecting agent, and butylamine black powder is as supplementary catching agent.Pass through
Using the use of combined capturing and collecting agent, in the case that concentrate grade is stablized or even is improved by a small margin, the recycling of three kinds of metals of lead zinc-silver
Rate increases substantially, while improving content of the silver in lead concentrate, and economic benefit is obviously improved.
For the present invention in the case where reagent cost is basically unchanged, mineral processing index has raising by a relatively large margin, lead concentrate product
Position 50% or so, the rate of recovery of lead are improved from 86% to 91%, and the silver-colored rate of recovery is improved from 45% to 52% in lead concentrate；Zinc essence
Mine grade 40% or so, the rate of recovery of zinc are improved from 87% to 90%, and the silver-colored rate of recovery is improved from 35% to 37% in zinc concentrate.
Various medicaments are applied in combination, and corresponding beneficiation reagent cost is basically unchanged, or even reduce about 0.5 yuan/ton, ore dressing
After the rate of recovery improves, the output value monthly increases 400,000 yuan.
