Description
First, technical field
The present invention relates to the preparing technical field of beneficiation reagent, specifically a kind of preparation method of smaltite inhibitor.
2nd, background technology
Often contain a small amount of smaltite in some lead-zinc deposits, because this part smaltite content is less, typically do not adopt
Use independent flotation, be often enriched in lead concentrate, then after lead smelting, extract cobalt element from lead skim again；Due in smaltite
Containing arsenic element, not only lead recovery is had an impact in lead smelting process, must be added to dearsenization system, so virtually simultaneously
Increased lead smelting cost, therefore, in sales process, cobalt element not only will not be valuated, also can reduce lead dot price on the contrary
Lattice, affect ore dressing economic benefit.If lead cobalt is carried out FLOTATION SEPARATION in ore dressing plant, obtain lead concentrate and cobalt concentrate, can not only
Improve the economic benefit in ore dressing plant, and lead cobalt is separated there is certain theory and practice meaning.
3rd, content of the invention
It is an object of the invention to provide a kind of preparation method of arsenic cobalt inhibitor, the inhibitor being prepared into can suppress arsenic
Cobalt ore, does not produce inhibitory action to galena, so that lead cobalt bulk concentrate is easily isolated and obtains lead, cobalt concentrate.
The present invention employs the following technical solutions and reaches above-mentioned purpose：A kind of preparation method of mispickel inhibitor, including
Following steps：
(1) 20～25g diaminourea tritan. being added to 100～120ml mass concentration is 15～20% sodium hydroxide
In solution, being heated to 40～45 DEG C makes it be cooled to 15～20 DEG C after dissolving, and is slowly added to 10～15ml mass at this temperature
Percentage concentration is that 10% ascorbic acid solution obtains product 1；
(2) 15～20g methyl orange being added to 80～90ml mass concentration is in 15～20% sodium sulfide solutions, is heated to
40～45 DEG C make its be cooled to after dissolving 15～20 DEG C product 2；
(3) by 5～6g sodium humate add product 2 so that it is dissolved product 3, by product 1 with product 3 in pH10.5～11
Under the conditions of coupling obtain black powder soluble in water be described smaltite inhibitor.
Slurry pH is adjusted to be 8～8.5 during flotation；In floatation process, described smaltite inhibitor is added to the mixing of lead cobalt
Carry out FLOTATION SEPARATION in concentrate,
The total consumption of described mispickel inhibitor is：500～600g/t.
During use, described smaltite inhibitor is first configured to the aqueous solution that mass percentage concentration is 1～2%.
Unless otherwise indicated, percentage ratio of the present invention is mass percent, and each constituent content percent sum is
100%.
Particularly advantage of the invention is：
1st, the smaltite inhibitor being prepared into can have good inhibiting effect to smaltite, does not produce suppression to galena
Effect, improves mineral resources comprehensive utilization.
2nd, dosing is few, nontoxic pollution-free.
