Description
Technical field
The present invention relates to the floatation process of a kind of high-sulfur containing gold and silver lead-zinc polymetallic sulfide ore, be suitable for high-sulfur containing gold and silver lead-zinc polymetallic sulfide ore flotation applications.
Background technology
High-sulfur is complicated containing gold and silver lead-zinc polymetallic sulfide ore ore properties, its major metal mineral magnetic iron ore, pyrite, zincblende, mispickel and galena etc., main gangue mineral is carbonate mineral and the quartz etc. such as calcite, sparring stone, and gold sulphide ores is rusty gold, electrum and kustelite.Gold silver mineral and sulfide in close relations, especially more close with galena, mispickel relation, and disseminated grain size is comparatively thin, between gold silver mineral and gold-carrying minerals and more difficult sorting between sulfide mineral.High-sulfur multi-metal sulfide due to metal-containing minerals many, sulfur content is high, disseminated grain size is thin, and symbiosis is close, each sulfide mineral is easily floating and floatability gap is little, and the mutual content of each concentrate is high, and sorting difficulty is large, and be easy to argillization after carbonate mineral ore grinding, also can bring certain negative effect to flotation.
More containing the beneficiation research of gold and silver lead-zinc polymetallic sulfide ore to high-sulfur, adopt diffeential floatation one by one, bulk flotation-separating technology again: when namely adopting direct diffeential floatation more, first select galena thing, suppression zincblende, troilite can heighten pulp alkalinity with lime, affect gold, silver and reclaim; Bulk flotation is when mixed choosing, and the floatability gap between after each mineral adsorpting formulation is less; Bulk concentrate by reagent removal and need add the gap that a large amount of inhibitor produces floatability between mineral when being separated, the difficulty of sorting increases, the mutual content of concentrate improves, be separated at gold-plumbous, lead-zinc be separated, zinc-sulphur content from time, commonly use poisonous and hazardous inhibitor such as heavy cadmium acid potassium, cyanide etc., very big to environmental hazard.
For solving the problem, someone adopts, and the plumbous silver of gold is preferential mixes floating-bulk concentrate separating technology, many employings Gravity separation when Gold Concentrate under Normal Pressure is separated, extraction of gold by cyanidation is the method such as flotation again, as Chinese patent CN93105622.5 " disclosed " a kind of beneficiation method containing golden multi-metal sulfide ", this method adopts gold, silver, copper, lead minerals diffeential floatation-Gravity separation, isolate containing gold with table concentration, the lead concentrate product of silver, mine tailing is copper concentrate product, but it is golden to there is containing of Gravity separation in this method, silver, plumbous, the each element of copper essence is mutually containing causing the rate of recovery low, reselection operation water requirement is large, operating efficiency is low waits deficiency.And for example Chinese patent CN201410238226.5 disclosed " a kind of beneficiation method of complex multi-metal silver sulfide gold mine synthetical recovery ", this method adopts Knelson concentrator gravity treatment to reclaim coarse granule gold-gravity tailings suppression zincblende, flotation of pyrite gold lead bronze-Jin lead bronze bulk concentrate is cyanidation gold-extracted-and cyanidation tailings suppresses copper, sulphur preferentially selects lead-activation to select the plumbous mine tailing of copper-select to activate and selects zincblende, because this method is to the synchronous floating and enriching of golden lead bronze mineral, and then be separated, be separated and adopt cyaniding, gravity treatment, flotation practice, so there is complex process, use cyanide poisonous to bad environmental, gravity treatment has the rate of recovery low equally, reselection operation water requirement is large, operating efficiency is low waits deficiency.
So the System of Flotation Reagent such as the inhibitor of reasonable, selective good collecting agent is high-sulfur contain gold and silver lead-zinc polymetallic sulfide ore valuable mineral be separated key.
Research and develop such high-sulfur of a kind of rational exploitation and utilization for this reason and just seem particularly urgent containing the floatation process of gold and silver lead-zinc polymetallic sulfide ore ore.
Summary of the invention
Task of the present invention is the deficiency in order to overcome existing technique, provides a kind of high-sulfur containing the floatation process of gold and silver lead-zinc polymetallic sulfide ore.
Task of the present invention has been come by the following technical programs:
High-sulfur is containing the floatation process of gold and silver lead-zinc polymetallic sulfide ore, and operation and condition are carried out as follows successively:
A. ore grind grading: first the tcrude ore after fragmentation and water are fed ball mill in the ratio of 1:1 and first carry out ore grinding, being milled to fineness is the breeze grain that-0.074mm accounts for 70%, then carries out classification to the breeze grain ground, and separates overflow substance and sand setting;
B. golden lead sorts: add inhibitor zinc sulfate 300 ~ 600g and sodium sulfite 500 ~ 800g successively to overflow substance per ton, collecting agent BK301 about 20 ~ 60g and butyl ammonium aerofloat 3 ~ 10g, foaming agent terpenic oil 20g carries out golden lead and roughly selects, obtain the plumbous bulk concentrate of gold and silver and the plumbous bulk concentrate of gold and silver, respectively collecting agent BK301 about 10 ~ 30g is added to gold and silver lead mixing mine tailing per ton, foaming agent terpenic oil 5 ~ 15g carries out golden lead and scans, obtain froth pulp and gold lead scans mine tailing, lime 400 ~ 800g is added to the plumbous bulk concentrate of gold and silver per ton, carry out golden lead concentrate separation, obtain gold and silver lead concentrate and Gold Concentrate under Normal Pressure,
C. zinc sorts: scan mine tailing to golden lead per ton and add inhibitor lime 4 ~ 6Kg and sodium sulfite 600 ~ 1000g successively, activator copper sulphate 300 ~ 800g, collecting agent butyl xanthate 20 ~ 50g and BK301 about 10 ~ 50g, foaming agent terpenic oil 10 ~ 40g carries out zinc and roughly selects, obtain zinc rougher concentration and zinc rougher tailings, respectively collecting agent butyl xanthate 10 ~ 20g and BK301 about 10 ~ 20g is added to zinc rougher tailings, foaming agent terpenic oil 20 ~ 40g carries out zinc and scans, obtain zinc and scan mine tailing and zinc scavenger concentrate, zinc carries out to zinc rougher concentration selected, obtain zinc concentrate and zinc cleaner tailing,
D. sulphur sorts: scan to zinc per ton that mine tailing adds sulfuric acid 4 ~ 6Kg, collecting agent butyl xanthate 50 ~ 100g successively, foaming agent terpenic oil 10 ~ 40g carries out sulphur and roughly selects, obtain sulphur rougher concentration and sulphur rougher tailings, carry out sulphur to sulphur rougher tailings respectively to scan, obtain sulphur and scan froth pulp and final tailings, sulphur carries out to sulphur rougher concentration selected, obtain sulphur cleaner tailings and iron concentrate.
The percentage related in description is mass percent.
The present invention compared with prior art has the following advantages and effect:
1. obtain gold and silver lead concentrate and Gold Concentrate under Normal Pressure in advance, owing to utilizing the floatability gap of ore Minerals, adopt plumbous preferential the mixing of gold and silver to float-separating technology.
2. the recovering effect of gold and silver lead is splendid, and select BK301 and butyl ammonium aerofloat 10:1 combined capturing and collecting agent in mass ratio because golden lead sorts, BK301 is by force selective, and butyl ammonium aerofloat can increase the viscosity of flotation froth.
3. from the mineral of high-sulfur, well can sub-elect zincblende, because zinc flotation adopts BK301 and butyl xanthate 1:1 combination medicament in mass ratio, BK301 is by force selective, and butyl xanthate collecting ability is strong.
4. the medicament selected is nontoxic, environmentally friendly, fully can reclaim the valuable mineral in ore, can also obtain zinc concentrate, iron concentrate except obtaining gold and silver lead concentrate and Gold Concentrate under Normal Pressure.
