Abstract
A method for flotation removal of coronadite out of manganic concerntrate comprises the following steps of adopting sodium hexametaphosphate to serve as a dispersing agent, utilizing water glass to serve as an inhibitor of a manganese mineral, utilizing sodium sulfide to be combined with hydroximic acid to serve as an activating agent of the coronadite, and using pentyl xanthate to be combined with octadecylamine to serve as a coronadite collecting agent; in the flotation process, regrinding the manganic concerntrate to mineral monomer separation, first adding sodium hexametaphosphate to scatter pulp, adding water glass to serve as an inhibitor of the manganese mineral, adding sodium sulfide and hydroximic acid to serve as an activating agent, and finally adding pentyl xanthate and octadecylamine to collect the coronadite, wherein tailings are manganic concerntrate products low in lead content. By the adoption of the method, the coronadite in the manganic concerntrate can be effectively removed, and the content of lead in the manganic concerntrate in the tailings is reduced. On the conditions that the feeding lead content is 5.34-7.53% and the manganese content is 27.83-28.50%, by performing roughing one time, scavenging twice and selection twice, the manganic concerntrate containing 28.60-29.40% of manganese, 1.02-1.16% of lead and having the recovery rate of 85.20-87.12% is obtained.
Description
First, technical field
The present invention relates to a kind of from manganic concerntrate flotation go demanganization lead ore method it is adaptable to need reduce manganic concerntrate in lead
The method for floating of content.
2nd, background technology
The essential mineral industrially extracting manganese metal is pyrolusite, psilomelane, but is usually present in nature Ore
A small amount of manganese lead ore is mixed in manganic concerntrate, due to lead element be manganese smelt when harmful element, so smelt before must as far as possible by
Lead element removes, in addition, manganese lead ore is close with the physical property of pyrolusite, psilomelane, by magnetic separation, gravity treatment can not be effective by it
Separate, only by the difference of its surface floatability, using method for floating, by adjusting floatation process and floating agent by manganese lead
Ore deposit FLOTATION SEPARATION, so not only reduces the harm that lead is smelted in smelting to manganese Metal, also increases business economic effect simultaneously
Benefit.
3rd, content of the invention
It is an object of the invention to provide a kind of method that demanganization lead ore is removed in flotation from manganic concerntrate, it can reduce manganese essence
Lead content in ore deposit, reduces the harm of lead element and smelting cost during manganese is smelted, and increases the leaching rate of manganese element.
The present invention employs the following technical solutions and reaches above-mentioned purpose: a kind of from manganic concerntrate flotation go to the side of demanganization lead ore
Method, comprises the following steps and regime of agent:
(1) use sodium hexameta phosphate as dispersant,
(2) make the inhibitor of manganese mineral with waterglass,
(3) use the activator of sodium sulfide and hydroximic acid group cooperation manganese lead ore
(4) amyl group xanthate and 18-amine. group cooperation manganese lead ore collecting agent are used,
(5), in floatation process, manganic concerntrate is regrinded to mineral monomer dissociation, first plus ore pulp is disperseed by sodium hexameta phosphate
Afterwards, the inhibitor of manganese mineral made by the glass that then adds water, and adds sodium sulfide and hydroximic acid and makees activator, finally plus amyl group xanthate and
18-amine. carries out collecting to manganese lead ore, and mine tailing is then leaded relatively low manganic concerntrate product,
(6) dosing is:
During use, described medicament is first configured to following concentration expressed in percentage by weight:
Unless otherwise indicated, percentage ratio of the present invention is mass percent, and each constituent content percent sum is
100%.
The present invention has the prominent advantages that:
1st, can effectively remove the manganese lead ore in manganic concerntrate, reduce the lead content of manganic concerntrate in mine tailing.
2nd, flowage structure of the present invention is simple, and dosing is few, less energy consumption.
