Four, description of drawings:
Accompanying drawing is a process chart of the present invention.
Five, the specific embodiment:
The present invention is described in further detail below in conjunction with accompanying drawing: referring to accompanying drawing, the technological process of Hg-Sb floatation separation method for Hg-Sb symbiotic sulfide ore of the present invention is: raw ore → muck → grind grading → bulk flotation → bulk concentrate reagent removal → selectivity inhibition → separating flotation → essence mine dehydration.Respectively each step in the technological process is described in further detail below: 1, muck: diameter is handled being crushed to greater than 50 millimeters lump ore, be crushed to fine ore stone with hammer mill again less than 10 millimeters less than 50 millimeters; 2, grind grading: will award one section closed circuit grinding of ball mill and spiral classifier formation through chute feeder less than 10 millimeters fine ore stone, after the ore milling product classification, ball mill is returned in sand return, the classification overflow feeds the bulk flotation operation, the classification effluent concentration is 30%, and the classification overflow fineness is less than 0.074 millimeter 75%; 3, bulk flotation: classifier overflow adds the activator plumbi nitras in tank diameter, carry out the abundant effect of floating agent and mineral surfaces behind collecting agent butyl xanthate and the foaming agent terpenic oil, ore pulp enters flotation device and carries out bulk flotation then, scan the back through one roughing, triple cleaning and secondary and discharge mine tailing, bulk concentrate enters the reagent removal operation.Table 1 is the regime of agent in the bulk flotation, and table 2 is running parameters of preparation equipment in the bulk flotation; 4, reagent removal: bulk concentrate enters tank diameter through after the bulk flotation, in order to deviate from the beneficiation reagent in the bulk concentrate, adds the reagent removal agent and stir reagent removal in bulk concentrate, and pulp density is 10%, and reagent removal agent consumption is 250 gram/tons, and the reagent removal time is 2.5 hours; 5, selectivity suppresses: in order to reach the purpose of mercury antimony FLOTATION SEPARATION, the stibnite in the bulk concentrate after the reagent removal is added potassium bichromate carry out the selectivity inhibition in tank diameter.Pulp density was 10% during selectivity suppressed, and the potassium bichromate consumption is 1000 gram/tons, and the inhibition time is 1.25 hours; 6, separating flotation: the bulk concentrate through reagent removal and inhibition stibnite adds butyl xanthate, terpenic oil in tank diameter, enter flotation device and carry out separating flotation, through behind one roughing, triple cleaning and the once purging selection, can obtain high-grade mercury concentrate and antimony concentrate, in for the first time selected and for the second time selected, need to add potassium bichromate.Table 3 has provided the regime of agent in the separating flotation, and table 4 is the running parameter of preparation equipment in the separating flotation circulation; 7, essence mine dehydration: the mercury concentrate enters in the sedimentation basin and precipitates, and primary water is entered Bilge, then regularly with settled mercury concentrate pack.Antimony concentrate is sent into the drum type brake filter again and is filtered after driven type concentrator dehydration in center concentrates.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, utilize beneficiation method to carry out mercury antimony Hg-Sb symbiotic sulfide ore industrial separation first, technology is simple, has reduced found the factory investment and production cost, and environmental pollution also obviously alleviates, and economic benefit and social benefit are all very remarkable.
2, adopt rational reagent removal prescription and reagent removal technology, the mercury antimony in the bulk concentrate is effectively separated, the mercury concentrate of acquisition is mercurous 65%, and antimony concentrate contains antimony 55%, and the rate of recovery of mercury reaches 82.17%, and the rate of recovery of antimony reaches 90.11%, and effect is fairly obvious.
3, mercury antimony symbiotic sulfide ore is smelted after technology ore dressing of the present invention separates, and has reduced smelting cost, and the product overall recovery also increases substantially finished product mercury rate of recovery raising 20.85%, antimony recovery raising 7.43%.
