Abstract
The present invention is a kind of beneficiation method that contains golden multi-metal sulfide, adopt the flotation speed difference of control mineral, the preferential emersion of gold, silver, copper, lead minerals that will easily float with micro-collecting agent, utilize the difference in specific gravity of gold, silver, lead and copper mineral then, isolate the lead concentrate product that contains gold, silver with gravity treatment on shaking table, mine tailing is the copper concentrate product.
Description
The present invention is a kind of beneficiation method that contains golden multi-metal sulfide, and float-gravity separation technology in particularly a kind of gold, silver, lead sulfide, copper and sulphur ore deposit that contains.
Containing multi-metal sulfide such as gold and silver copper-lead sulphur is a kind of easily floating and approaching sulphide ore of flotation speed, often with bulk flotation concentrate output, but the unusual difficulty of sorting.The medicament of this class ore of sorting reagent removal in advance commonly used both at home and abroad-heat or heavy dose of vulcanized sodium desorb, washing mineral surfaces, recover mineral floatability difference, ratio or inhibition lead minerals in copper, lead minerals content floats copper then, or it is floating plumbous to suppress copper mineral, reaches the purpose of sorting.Some mines are arranged because heavy metal ion content is too high, disturb the flotation speed of different minerals, thereby separated difficulty, can't realize sorting as stated above, can only produce a kind of bulk concentrate (intermediate products) of multi-metal sulfide, not reach the basic demand of smelting.
The objective of the invention is to avoid providing outside the above-mentioned deficiency of the prior art a kind of floating-heavy separating technology that contains golden multi-metal sulfide, to reach sorting lead, copper, sulfur mineral from contain golden multi-metal sulfide.
The purpose of invention can reach by following measure: the flotation speed difference that adopts the control mineral, the preferred emersion of gold, silver, copper, lead minerals that will easily float with micro-collecting agent, utilize the difference in specific gravity of gold, silver, lead and copper mineral then, isolate the lead concentrate product that contains gold, silver with gravity treatment on shaking table, mine tailing is the copper concentrate product.Its technical process is as follows:
(1) add lime in grinding process, control ore pulp Ph is greater than 7;
(2) add the butyl xanthate of 5～10g/T in giving flotation classification overflow ore pulp, the foaming agent of 50～80g/T stirs 5 minutes with Au, Ag, Cu, Pb mineral emersion;
(3) give floating mine tailing by flotation of pyrite condition (vulcanized sodium 75～100g/T, butyl xanthate 75～120g/T, foaming agent 80～120g/T) flotation concentrate products;
(4) in giving the gold, silver of emersion, copper, plumbous froth pulp, add ferrous sulfate 200～400g/T, vulcanized sodium 600～1000g/T, phosphorus pentasulfide 100～200g/T stirred 15～30 minutes;
(5) control pulp density 15～20% feeds shaking table and carries out sorting, table concentrate band output for containing the lead concentrate of gold, silver, shaking table mine tailing output be the copper concentrate product.
Fig. 1 is the floating-gravity separation technology process principle figure that proposes according to invention.
The present invention is further detailed in conjunction with the accompanying drawings below:
Floating-gravity treatment process integration has carried out small-scale test, has obtained good separating effect as described in the present invention.This ore deposit contains Au grade 5.6g/T, Ag grade 58.15g/T, Cu grade 0.55%, Pb grade 9.48%, S grade 3.76%, in grinding process, add lime, control ore pulp Ph adds micro-collecting agent butyl xanthate 7g/T, foaming agent 70g/T then greater than 7, gives and selects Au, Ag, Cu mineral earlier.Product adds vulcanized sodium 80g/T, butyl xanthate 100g/T, foaming agent 100g/T, flotation sulphur product in the groove.Au, the Ag, Cu, the Pb mineral that give first emersion add ferrous sulfate 300g/T, vulcanized sodium 800g/T, phosphorus pentasulfide 150g/T again, stir 30 minutes, and adjustment pulp density 15～20% is sent into shaking table and carried out sorting.Obtain through small-scale test: it is 75-77% that lead concentrate contains the Pu grade, contain more than the Au grade 40g/T, more than the argentiferous grade 550g/T, contain copper grade 1-1.6%, lead recovery 76-79% obtains copper concentrate and contains copper grade in 10-12%, contain gold grade 20g/T, leaded grade 7-8% copper recovery 60-63% obtains sulphur concentrate sulfur-bearing grade 30-33%, and sulphur returns rate 22-25%.Technology of the present invention is carried out local lead bronze mineral shaking table separation test in mine, somewhere, China Central Plains, obtain the plumbous grade 75% of lead concentrate, and the qualitative test of copper grade 8% is just preparing to carry out the industrialness pilot production at present.
This technology simple technique index is stable, and consumption pharmacopoeia class quantity all is lower than bulk flotation, easy operating control.And technical indicator is higher than complete floating index (impurity content) cost that separates also than the low 20-40% of bulk flotation.
