Abstract
The invention discloses a preparation method for a cassiterite mineral collector. The preparation method comprises the following steps of weighing aniline, phosphoric acid and nitric acid according to a molar ratio of (1-2):(3-4):(3-7), placing the aniline, the phosphoric acid and the nitric acid into a gas generator, collecting generated gas, introducing the generated gas into a high-pressure reaction kettle containing C12-16 fatty alcohol in such a manner that the molar ratio of the fatty alcohol to the gas is kept to be (1-2):(2-5), performing reaction for 3 to 5h under the conditions of pressure of 8 to 9Mpa and temperature of 450 to 500 DEG C, and distilling an obtained liquid mixture to collect distillate of 250 to 300 DEG C under normal pressure to obtain a viscous liquid substance, namely the cassiterite mineral collector. According to the preparation method, the collector can be used for efficiently recovering cassiterite minerals under the condition of a small amount of activator, and the total yield of the cassiterite minerals reaches more than 85 percent.
Description
One, technical field
The present invention relates to the preparing technical field of beneficiation reagent, specifically a kind of preparation method of cassiterite mineral collector.
Two, background technology
The recovery of cassiterite mineral generally adopts reselecting method both at home and abroad at present, and person of high grade adopts shaking table directly to reclaim after ore grinding, and the ore that grade is low adopts shaking table to reclaim after then first adopting jigging to throw tailing regrind.But because cassiterite mineral is crisp, in grinding process, the overground shaking table of a part of cassiterite more or less can be made to reclaim and to run off in mine tailing, the annual fine fraction cassiterite run off in mine tailing is worth tens billion of, if adopt selective copper collector to be reclaimed by these fine fraction tin-lead soldering, this has important practical significance to the recovery of cassiterite resource.
Three, summary of the invention
The object of the present invention is to provide a kind of preparation method of cassiterite mineral collector, the flotation that it can realize cassiterite mineral under adding a small amount of salicylaldoxime to make the condition of activator is reclaimed.
The present invention realizes above-mentioned purpose by the following technical solutions: a kind of preparation method of copper-nickel sulfide mineral collecting agent, comprises the steps:
Take aniline in molar ratio: phosphoric acid: nitric acid=1 ~ 2:3 ~ 4:3 ~ 7, put into gas generator, collect produce gas pass into 12 ~ 16 C fatty alcohols are housed autoclave in, the mol ratio of fatty alcohol and gas keeps 1 ~ 2:2 ~ 5, is 8 ~ 9Mpa at pressure, and temperature is react 3 ~ 5h under 450 ~ 500 DEG C of conditions, the liquid mixture obtained, distill cut between collection 250 ~ 300 DEG C at ambient pressure, obtain a kind of thick liquid substance, be the collecting agent of cassiterite mineral.
During flotation, the back end hydrogenation sodium oxide molybdena that dissociated by ore ore grinding to mineral monomer adjusts slurry pH to 8 ~ 8.5, then add gangue mineral to suppress, then add the agent of cassiterite mineral activation, finally add described cassiterite mineral collector and foaming agent and collecting is carried out to cassiterite mineral obtain cassiterite concentrate.
The total consumption of described collecting agent: 350 ~ 450g/t.
Unless otherwise indicated, percentage of the present invention is mass percent, and each constituent content percentage sum is 100%.
The present invention has the following advantages:
1, described flotation collector is soluble in water, and has good selective and resistance to low temperature.
2, only need a small amount of activator just can carry out collecting to cassiterite mineral, reduce reagent cost.
3, owing to being only need a small amount of activator, the recovery therefore for micro fine particle mineral is significant, and the rate of recovery of general cassiterite mineral can reach more than 85%.
