Description
Technical field
The present invention relates to a kind of beneficiation method, more particularly to silver, copper, sulphur and tin are recycled in a kind of tin silver symbiosis polymetallic ore
Beneficiation method.
Background technology
Associated Constituents are more altogether in tin ore, and embedding cloth relationship is complicated, and mineralogical property is different, cause separation condition different, are to make
The main reason for ore dressing being difficult at such ore.On the one hand, cassiterite is crisp frangible, and easily argillization or excessively crushing generate a large amount of
Secondary slime is difficult to recycle, and results in waste of resources；On the other hand, the sulphide ore of association is but difficult to resolve from hardly possible separation altogether in ore, if
Obtaining high target concentrate then needs separative selection under the conditions of fine grinding.In order to solve this to contradiction, need to pay close attention in ore dressing process
And the mistake crushing phenomenon of cassiterite is avoided, and improve the separation index of Associated Constituents altogether as much as possible by the optimal control of technique,
Therefore close effective combination of fineness, flow and medicament is then most important.
About in the ore dressing document report of cassiterite, mostly recycled with micro fine particle based on, it is floating to have worked out single flotation, magnetic
Joint, weight Combination of magnetic separation flotation technique, and it is directed to the extremely non-uniform tin silver symbiosis polymetallic ore of disseminated grain size, still it is to see that ore dressing is comprehensive at present
Close the document report of recovery technology.
Invention content
The purpose of the present invention is to provide in a kind of tin silver symbiosis polymetallic ore recycle silver, copper, sulphur and tin beneficiation method,
Be finally obtained silver preparation concentrate, Tin concentrate and iron concentrate, realize valuable element in tin silver symbiosis polymetallic ore effective enrichment and
Synthetical recovery.
The beneficiation method of the present invention comprises the steps of：

Mine；Silver-colored rougher concentration carries out primary cleaning, obtains silver-colored primary cleaning concentrate and silver-colored primary cleaning chats, and silver-colored primary cleaning chats returns
It is back to roughing operation and forms closed cycle；Silver-colored primary cleaning concentrate regrinding mine accounts for 75~85% to fineness -0.043mm, and carbon is added
Sour sodium control ph is that 8~9, successively 0~10 g ton of collecting agent and 0~5 g ton of foaming agent carry out selected roughing, is obtained respectively
Selected rougher concentration and selected rougher tailings；Selected rougher concentration carries out the selected acquisition silver preparation concentrate of blank three times, selected roughing tail
Mine carries out blank three times and scans acquisition sulphur chats；The chats at different levels sequence obtained is back to parent job；
3. sulphur flotation：Sulfuric acid is added in silver floatation tailing to size mixing, control ph is 6~7, sequentially adds collecting agent
50~100 g tons and 10~60 g ton of foaming agent terpenic oil carry out sulphur roughing flotation, obtain sulphur rougher concentration and sulphur roughing tail
Mine；Sulphur rougher tailings is added 20~50 g ton of collecting agent and carries out once purging selection, obtains sulphur once purging selection chats and sulphur scans tail
Mine, sulphur once purging selection middling recurrence to sulphur roughing flotation operation form closed cycle；Sulphur rougher concentration is followed by empty three times
Bai Jingxuan, obtains iron concentrate, and the selected chats sequences at different levels of acquisition are back to parent job；
4. cassiterite gravity treatment：Sulphur scans tailing and is classified as+0.074mm and two grades of -0.074mm；+ 0.074mm grades into
Row spiral chute gravity treatment obtains spiral chute rough concentrate and spiral chute tailing；Spiral chute rough concentrate carries out table concentration, obtains
Obtain cassiterite table concentrate and shaking table tailing；
5. sulphur is floated in desliming：10~500 g ton of dispersant waterglass is added in -0.074mm grades to size mixing, then is revolved
Device desliming is flowed, cyclone overflow and hydrocyclone sand are obtained；It is 25~33% that hydrocyclone sand, which is sized mixing to pulp density, successively
100~200 g ton collecting agent butyl xanthates and 20~100 grams of foaming agent terpenic oils are added, carry out roughing flotation, it is floating to obtain sulphur
Concentrate selection and sulphur flotation tailing；
6. tin-lead soldering：It is 20~25% that sulphur flotation tailing, which is sized mixing to pulp density, sequentially adds 50~3000 g tons
Regulator, 10~50 g ton supplementary catching agent tributyl phosphates carry out strong stirring and size mixing, and 1000~2000 g tons are added and catch
Agent and 40~110 g ton foaming agent terpenic oils are received, a roughing flotation is carried out, obtain roughing flotation concentrate and roughing flotation tail
Mine；Roughing flotation tailing pulp density is 18~24%, and 300~1200 g ton collecting agents, 0~50 g ton foaming agent pine is added
Alcohol oil carries out a flotation and scans, and obtains scavenger concentrate and scans tailing, scavenger concentrate is back to a roughing flotation operation shape
At closed cycle；Roughing flotation concentrate pulp a concentration of 5~10%, blank is selected three times for progress, obtains tin-lead soldering concentrate；Respectively
Grade flotation middling recurrence to parent job forms closed cycle；It is total cassiterite that cassiterite table concentrate and tin-lead soldering concentrate, which merge,
Concentrate.
Collecting agent is alkyl isothiourea, ethyl ammonia sulfate or butyl ammonium aerofloat in the silver flotation.
Foaming agent is methyl anyl alcohol, three polypropylene glycol methyl ethers or 1 in the silver flotation:1 terpenic oil:Methyl anyl alcohol.
Collecting agent is 4 in the sulphur flotation:1 butyl xanthate:Ethyl xanthate.
