Abstract
Floatation of antimony sulfide ore in slightly acidic medium belongs to antimony sulfide ore flotation field.With sulfuric acid or sulfurous acid, SO
2Adjust ore pulp to faintly acid, cooperate selective copper collector and lead salt activator, do not need foaming agent.Prescription is simple, and the medicine consumption is low, flotation speed is fast, and the sorting index height helps antimony-arsenic sorting.Single antimony sulfide ore (containing antimony 7.28%) flotation results, antimony concentrate grade 65%, the rate of recovery 98.2%, to containing the flotation of arsenic (0.55%) antimony sulfide ore, antimony concentrate contains arsenic and drops to 0.34%.
Description
The invention belongs to the antimony sulfide ore flotation.
The antimony sulfide ore flotation is carried out in neutral ore pulp usually, is activator with the plumbi nitras, and xanthate is a collecting agent, and terpenic oil is done foaming agent and formed traditional prescription.Nearly 6 kinds of more complicated prescription medications mix use with multiple senior sulphur hydrogen class collecting agent (as butyl xanthate, diethyldithiocarbamate etc.) and a large amount of supplementary catching agent (as shale oil, kerosene etc.), also need activator and foaming agent.Use this two classes prescription, flotation speed is slow, and floatation equipment is many, energy consumption is high; Floating agent is wide in variety, the medicine consumption is big; Floatation indicators low (external best index such as its ore deposit, Songyuan City grade 11% of South Africa Mel, antimony concentrate grade 61.94%, the rate of recovery 91.4%; Domestic index preferably such as China tin ore south of the mountains factory, raw ore contains antimony 3.19%, antimony concentrate grade 47.58%, the rate of recovery 93.97%), bad to the antimony sulfide ore sorting that contains arsenic, antimony concentrate contains the arsenic height (when antimony ore contains arsenic 0.58%, antimony concentrate contains arsenic 2.74%), influence antimony smelting recovery and antimony product quality, and environment is brought pollution nuisance.In addition, the SO of smeltery's discharge
2Pernicious gas also needs to administer and utilize.
In order to accelerate flotation speed, sorting antimony-arsenic mineral is simplified prescription, reduces the medicine consumption, improves floatation indicators, improves product quality, and the present invention adopts the faintly acid flotation of ore pulp.
Basic comprising of the present invention is: with sulfuric acid or sulfurous acid (SO
2) to adjust ore pulp suitable to the flotation antimony trisulfide to this pH value of faintly acid PH5～6(, and equipment is not had damage), with selective copper collector butyl ammonium aerofloat or other sulphur hydrogen class collecting agent flotation.When using butyl ammonium aerofloat, do not need foaming agent; During with sulphur hydrogen class collecting agent, still want foaming agent.Before antimony sulfide ore (comprising the antimony sulfide ore that the contains arsenic) flotation, press sulfuric acid (or sulfurous acid (SO
2)) 1000～4000 gram/tons, plumbi nitras 100～300 gram/tons, butyl ammonium aerofloat 150～300 gram/tons order add, and adjusts ore pulp; Through one roughing (5～10 minutes), once purging selection (3～5 minutes), primary cleaning, just can obtain the high-quality antimony concentrate.When raw ore contained antimony 4.5～7.2%, gained antimony concentrate grade was 60～65%, the rate of recovery 95～98%.When raw ore is when containing the antimony sulfide ore of arsenic 0.45～0.6%, the antimony concentrate arsenic content that flotation obtains is from the traditional prescription of 2.5～4.5%() be reduced to this prescription of 0.3～0.5%().
The present invention's following advantage of having compared with neutral flotation of ore pulp: 1. flotation time is short, and the medicine consumption is few.Antimony sulfide ore flotation in the faintly acid ore pulp (roughly selecting 10 minutes), antimony recovery can reach 97%; And flotation in neutral ore pulp (roughly selecting 10 minutes), the rate of recovery only 82.3%, even when collector dosage and flotation time doubled simultaneously, the rate of recovery still has only 94.3%.2. help antimony-arsenic sorting.When raw ore contains antimony 5.11%, arsenic 0.46%, do the antimony concentrate that collecting agent (needing foaming agent) obtained with xanthate and contain antimony 49.08%, arsenic 4.25%, antimony recovery 94.7%; Contain antimony 5.19%, arsenic 0.55% and work as raw ore, (do not need foaming agent) when doing collecting agent, can obtain antimony concentrate and contain antimony 56.1%, arsenic 0.34%, antimony recovery 95.6% with butyl ammonium aerofloat.It is low that antimony concentrate contains arsenic, helps shortening the antimony smelting cycle, reduces and smelt alkaline consumption and energy consumption, improves antimony smelting recovery and antimony product quality, alleviates the pollution of arsenic to environment.3. can utilize SO
2The acidity that waste gas, sulfurous acid, useless dilute sulfuric acid are adjusted ore pulp turns waste into wealth.
Embodiment: to containing the antimony sulfide ore raw ore of antimony 7.28%, before flotation, add sulfuric acid 2500 grams, plumbi nitras 150 grams, butyl ammonium aerofloat 180 gram adjustment ore pulps (PH=5.4) in proper order by ore per ton, through one roughing (10 minutes), once purging selection (5 minutes), primary cleaning, the small-sized closed circuit flotation experimental results that chats returns in proper order obtains antimony concentrate grade 65%, the rate of recovery 98.2%.
