Abstract

The method for floating of limonite is removed in a kind of concentrate from potassium feldspar, is comprised the steps：Using sodium hexameta phosphate as dispersant, make the inhibitor of potassium feldspar with mercaptopropionic acid sodium and acid black, hydroxamic acid is made the activator of limonite, combined with lauryl amine with enuatrol and make limonite collecting agent；In floatation process, first plus after ore pulp is disperseed by sodium hexameta phosphate, then plus mercaptopropionic acid sodium makees the inhibitor of potassium feldspar with acid black, add the activator that hydroximic acid makees limonite, finally plus enuatrol combines collecting limonite with lauryl amine, mine tailing is then potassium feldspar concentrate product that iron content is relatively low.The limonite in potassium feldspar concentrate can be effectively removed using the present invention, the iron content of potassium feldspar concentrate in mine tailing is reduced.Under the conditions of being 1.84～2.71%, potassium feldspar 88.10～89.36% to ore deposit iron content, triple cleaning is scanned three times through one roughing, iron content 0.15～0.18% is obtained, K-feldspar 91.30～92.54%, the response rate are 85.10～86.35% potassium feldspar concentrate.

Description

The method for floating of limonite is removed in a kind of concentrate from potassium feldspar
First, technical field
The present invention relates to the method for floating of limonite is removed in a kind of concentrate from potassium feldspar, it is adaptable to need to reduce potassium feldspar The method for floating of iron content in concentrate.
2nd, background technology
China's potassium feldspar rich in mineral resources, widely distributed and distribution Relatively centralized, becomes China's advantage nonmetallic minerals Resource.With the development of science and technology, potassium feldspar is widely used in commercial production.China is using potassium feldspar production glass, pottery The industries such as the side such as porcelain, chemical fertilizer, have strictly to the iron content in potassium feldspar raw material when being especially applicable to the industries such as glass, ceramics Requirement, the height of one side iron content not only affects the whiteness of product, while have an effect on the performance of product, if by potassium feldspar Iron content in raw material is reduced to a certain extent, can not only improve product quality, while can also improve product economy value, be enterprise Industry increases economic benefit.
3rd, the content of the invention
It is an object of the invention to provide the method for floating of limonite is removed in a kind of concentrate from potassium feldspar, it can reduce Iron content in potassium feldspar concentrate, improves potassium feldspar concentrate quality.
The present invention is employed the following technical solutions and reaches above-mentioned purpose：The flotation of limonite is removed in a kind of concentrate from potassium feldspar Method, raw materials used for potassium feldspar concentrate, in concentrate, iron content is 1.84～2.71%, potassium feldspar 88.10～89.36%, thing Facies analyses show, in addition to potassium feldspar, impure mineral is mainly limonite and a small amount of goethitum, aluminum silicon mineral and calcareous mineral,
Comprise the following steps and regime of agent：
(1) using sodium hexameta phosphate as dispersant,
(2) mercaptopropionic acid sodium and acid black make the inhibitor of wollastonite,
(3) hydroxamic acid makees the activator of limonite,
(4) combined with lauryl amine with enuatrol and make limonite collecting agent,
(5) in floatation process, first plus after ore pulp is disperseed by sodium hexameta phosphate, then plus mercaptopropionic acid sodium makees potassium with acid black The inhibitor of Anhydrite, adds the activator that hydroximic acid makees limonite, finally plus enuatrol combines collecting limonite with lauryl amine, Mine tailing is then the potassium feldspar concentrate product that iron content is relatively low,
(6) dosing is：
During use, the medicament is first configured to into following concentration expressed in percentage by weight：
Unless otherwise indicated, percentage ratio of the present invention is mass percent, and each component content percent sum is 100%.
The present invention's has the prominent advantages that：
1st, the limonite in potassium feldspar concentrate, the iron content in reduction mine tailing in potassium feldspar concentrate can effectively be removed.
2nd, flowage structure is simple, and dosing is few, less energy consumption.
4th, specific embodiment
