Description
Technical field
The present invention relates to a kind of beneficiation method, silver, copper, sulphur and tin are reclaimed in more particularly to a kind of silver-colored symbiosis polymetallic ore of tin
Beneficiation method.
Background technology
Associated Constituents are more altogether in tin ore, and embedding cloth relation is complicated, and mineralogical property is different, cause separation condition different, are to make
It is difficult to the main cause of ore dressing into such ore.On the one hand, cassiterite is crisp frangible, easily argillization or excessively crushing, produces substantial amounts of
Secondary slime is difficult to reclaim, and causes the wasting 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 avoid the mistake crushing phenomenon of cassiterite, and improve by the optimal control of technique the separation index of common Associated Constituents as much as possible,
Therefore close effective combination of fineness, flow and medicament is then most important.
On in the ore dressing document report of cassiterite, reclaimed more with micro fine particle based on, worked out single flotation, magnetic and floated
Joint, weight Combination of magnetic separation flotation technique, and for the disseminated grain size extremely uneven silver-colored symbiosis polymetallic ore of tin, at present still to see that ore dressing is comprehensive
Close the document report of recovery technology.
The content of the invention
It is an object of the invention to provide the beneficiation method that silver, copper, sulphur and tin are reclaimed in a kind of silver-colored symbiosis polymetallic ore of tin,
Be finally obtained silver preparation concentrate, Tin concentrate and iron concentrate, realize in the silver-colored symbiosis polymetallic ore of tin effective enrichment of valuable element and
Synthetical recovery.
The beneficiation method of the present invention is comprised the steps of：

It is back to roughing operation and forms closed cycle；Silver-colored primary cleaning concentrate regrinding ore deposit accounts for 75~85% to fineness -0.043mm, adds carbon
Sour sodium control ph is that 8~9, the successively g ton of collecting agent 0~10 and the g ton of foaming agent 0~5 carry out selected roughing, is obtained respectively
Obtain selected rougher concentration and selected rougher tailings；Selected rougher concentration carries out the selected acquisition silver preparation concentrate of three blank, selected roughing
Mine tailing carries out three blank and scans acquisition sulphur chats；The chats at different levels order obtained is back to parent job；
3. sulphur flotation：Add sulfuric acid in silver floatation mine tailing to be sized mixing, control ph is 6~7, sequentially adds collecting agent
50~100 g tons and the g ton of foaming agent terpenic oil 10~60 carry out sulphur roughing flotation, obtain sulphur rougher concentration and sulphur roughing tail
Ore deposit；Sulphur rougher tailings adds the g ton of collecting agent 20~50 and carries out once purging selection, obtains sulphur once purging selection chats and sulphur scans tail
Ore deposit, sulphur once purging selection middling recurrence to sulphur roughing flotation operation forms closed cycle；Sulphur rougher concentration is followed by three skies
Bai Jingxuan, obtains iron concentrate, and the selected chats orders at different levels of acquisition are back to parent job；
4. cassiterite gravity treatment：Sulphur scans mine tailing and is classified as+0.074mm and two grades of -0.074mm；+ 0.074mm grades are entered
Row spiral chute gravity treatment, obtains spiral chute rough concentrate and spiral chute mine tailing；Spiral chute rough concentrate carries out table concentration, obtains
Obtain cassiterite table concentrate and shaking table mine tailing；
5. sulphur is floated in desliming：The g ton of dispersant waterglass 10~500 is added in -0.074mm grades to size mixing, then is revolved
Device desliming is flowed, cyclone overflow and hydrocyclone sand is 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, roughing flotation is carried out, sulphur is obtained and floats
Concentrate selection and sulphur flotation tailing；
6. tin-lead soldering：By sulphur flotation tailing size mixing to pulp density be 20~25%, sequentially add 50~3000 grams/
Ton regulator, 10~50 g ton supplementary catching agent tributyl phosphates carry out strong stirring and sized mixing, and add 1000~2000 g tons
Collecting agent and 40~110 g ton foaming agent terpenic oils, carry out a roughing flotation, obtain roughing flotation concentrate and roughing flotation
Mine tailing；Roughing flotation mine tailing pulp density is 18~24%, adds 300~1200 g ton collecting agents, the foaming of 0~50 g ton
Agent terpenic oil carries out a flotation and scanned, and obtains scavenger concentrate and scans mine tailing, and scavenger concentrate is back to a roughing flotation work
Industry formation closed cycle；Roughing flotation concentrate pulp concentration is 5~10%, and three blank of progress are selected, obtains tin-lead soldering essence
Ore deposit；Flotation middling recurrences at different levels to parent job forms closed cycle；Cassiterite table concentrate and tin-lead soldering concentrate, which merge, is
Total cassiterite concentrate.
Collecting agent is alkyl isothiourea, ethyl ammonia sulfate or butyl ammonium aerofloat in the silver-colored flotation.
Foaming agent is methyl anyl alcohol, three polypropylene glycol methyl ethers or 1 in the silver-colored flotation:1 terpenic oil:Methyl anyl alcohol.
