Problems solved by technology

[0010] The purpose of the present invention is to provide a collector for collecting siliceous minerals and a preparation method thereof, to solve the problem that the existing mineral collector has a small pH adaptability range, poor selectivity, weak adaptability, and the collector is affected by ore slime. The impact of the flotation foam is relatively large, and the flotation foam is sticky, not easy to dissipate, and settle. Phosphogypsum, etc.) to achieve the purpose of floating the siliceous minerals in the ore from the flotation foam

Embodiment 1

[0028] Example 1: Mix pure quartz minerals and collophanite pure minerals at a ratio of 5:5, the grinding fineness of the two ores is -200 mesh > 70%, and the medicament system is: by weight tetradecyl trimethyl 1 part of ammonium bromide, 0.2 part of sodium dodecylsulfonate, 0.1 part of ether amine, 1 part of water, 0 part of sodium oleate, 0 part of dodecylamine, 0 part of hydrochloric acid, 0 part of polyetheramine, dodecyl 0 parts of sodium alkyl sulfate, 0 parts of diesel oil, 0 parts of tributyl phosphate. The dosage of medicine is 100g / t.

[0029] Get mixed ore 10g and add pure mineral flotation machine, press figure 1 way for flotation, silicon concentrate SiO 2 The content is 96%, and the recovery rate is 99%.

Embodiment 2

[0030] Embodiment 2: get the demagnesium-phosphorus concentrate after reverse flotation demagnesification of a phosphate ore flotation plant in Yunnan, press figure 2 Carry out desiliconization reverse flotation, use medicament system as: by weight 7 parts of cetyltrimethylammonium bromide, 1 part of sodium lauryl sulfate, 0.1 part of diesel oil, 1 part of tributyl phosphate, 1 part of water 0 parts, 0 parts of sodium oleate, 0 parts of dodecylamine, 0 parts of hydrochloric acid, 0 parts of polyetheramine, 0 parts of etheramine, 0 parts of sodium dodecylsulfonate. The dosage of the agent is 200g / t, and the indicators shown in the following table can be obtained by adopting the process of one roughing and one sweeping:

[0031]

Embodiment 3

[0032] Embodiment 3: get the phosphogypsum 200g that some wet-process phosphoric acid factory discharges in Yunnan and add flotation machine, press image 3 Carry out flotation to remove SiO contained in phosphogypsum 2 , to increase CaSO in phosphogypsum 4 2H 2 O purity. The pharmaceutical system is: by weight 1 part of cetyltrimethylammonium chloride, 0.5 part of polyetheramine, 1 part of sodium dodecylsulfonate, 1 part of water, 0 part of sodium oleate, 0 part of dodecylamine 0 parts, hydrochloric acid 0 parts, etheramine 0 parts, sodium lauryl sulfate 0 parts, diesel oil 0 parts, tributyl phosphate 0 parts. The dosage of the agent is 300g / t, and the SiO in the phosphogypsum can be removed by one rough selection. 2 The content was reduced from 15.7% to 1.4%. The specific indicators are shown in the table below:

Abstract

The invention discloses an efficient collecting agent for collecting siliceous ores. The main component of the efficient collecting agent is any one or more than two of alkyl halide ion (F, Cl, Br andI) type monoquaternary ammonium salts with the carbon chain length of 8-18; and the auxiliary components comprise sodium oleate, dodecylamine, hydrochloric acid, polyether amine, ether amine, sodiumdodecyl sulfate, lauryl sodium sulfate, diesel oil, tributyl phosphate and water. Main components and auxiliary components of the collecting agent are proportioned according to different treated oresand solid wastes (iron ores, phosphorite, fluorite, barite, phosphogypsum and the like), so that the purpose of floating siliceous minerals in the ores from flotation froth is achieved. The collectingagent is prepared without high temperature and high pressure, the pH application range is wide, the agent process can be greatly simplified, and the agent cost is saved; compared with an existing siliceous mineral collecting agent, the collecting agent is high in pH adaptability, good in siliceous mineral collecting selectivity and free of influences of slime, flotation froth is not sticky, and dissipation and sedimentation are easy.

Description

technical field [0001] The invention belongs to the technical field of collecting siliceous ore by flotation, in particular to a collector for collecting siliceous ore. Background technique [0002] Froth flotation is a widely used method of beneficiating ores containing valuable minerals (commonly referred to as "valuable minerals"). Valuable minerals refer to a metal, metals, mineral or minerals that are the main purpose of the flotation process, that is, metals and minerals that need to remove impurities. [0003] A typical froth flotation process involves intermixing an aqueous slurry containing finely ground ore particles with a frother or blowing agent to create froth. Ore particles containing valuable minerals are preferentially attracted to the foam due to the affinity between the foam and the minerals exposed on the surface of the ore particles. The valuable minerals are then collected by separating them from the froth. Chemical agents called "collectors" are oft...
