Embodiment 1

[0012] Embodiment 1, the method for cleaning the surface of the feldspar or quartz mineral is carried out according to the following steps: the first step, the feldspar or quartz concentrate is mixed with water into an ore slurry with a mass concentration of 10% to 50%; in the second step, according to Add 50g to 1000g of N-acyl sarcosine sodium per ton of feldspar or quartz concentrate, weigh N-acyl sarcosine sodium, and prepare the weighed N-acyl sarcosine sodium with water to a mass concentration of 5% to 5%. 10% cleaning solution; in the third step, add the cleaning solution to the ore pulp, and stir in the flotation machine for 5 to 40 minutes for flotation cleaning. minerals, and the product in the tank is cleaned feldspar or quartz concentrate. N-acyl sarcosine sodium according to the "Preparation, performance and application of N-acyl sarcosine sodium" published by Xu Hujun, Lian Ying, Du Zhen et al. Obtained by the preparation method mentioned in.

Embodiment 2

[0013] Embodiment 2, the method for cleaning the surface of the feldspar or quartz mineral is carried out according to the following steps: the first step, the feldspar or quartz concentrate is mixed with water to form a slurry with a mass concentration of 10% or 50%; in the second step, press Add 50g or 1000g of N-acyl sarcosine sodium per ton of feldspar or quartz concentrate, weigh N-acyl sarcosine sodium, and prepare the weighed N-acyl sarcosine sodium with water to a mass concentration of 5% or 10% cleaning solution; in the third step, add the cleaning solution to the ore pulp, stir in the flotation machine for 5 minutes or 40 minutes for flotation cleaning, and after the flotation cleaning is completed, foams are obtained respectively, that is, the iron that is removed by flotation minerals, and the product in the tank is cleaned feldspar or quartz concentrate.

Embodiment 3

[0014] Embodiment 3, the difference with the above-described embodiment is that after preparing the slurry and before the second step, add 100g to 1000g sodium carbonate per ton of feldspar or quartz concentrate to weigh the sodium carbonate, and the weighed The sodium carbonate is prepared with water to make a sodium carbonate aqueous solution with a mass concentration of 1% to 20%, and the sodium carbonate aqueous solution is added to the pulp, and after stirring and mixing evenly, the prepared cleaning solution is added to it.

Abstract

The invention relates to the technical field of ore surface cleaning, in particular to a feldspar or quartz surface cleaning method. The feldspar or quartz surface cleaning method comprises the following steps of firstly mixing feldspar or quartz concentrates with water to form pulp with the mass concentration ranging from 10% to 50%; weighing N-acyl sodium cocoyl sarcosinate and mixing the weighed N-acyl sodium cocoyl sarcosinate with water to prepare a cleaning solution; adding the cleaning solution into the pulp, mixing the mixture in a flotation machine to perform flotation cleaning, respectively obtaining foam, namely removed irony ores and an in-groove product, namely cleaned feldspar or quartz concentrates after flotation cleaning. The feldspar or quartz surface cleaning method enables the loss rate of the feldspar or quartz concentrates in irony ore impurity products to be remarkably reduced, enables used medicaments to be naturally degraded, has small environmental pollution and is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of mineral surface cleaning, and relates to a method for cleaning the surface of feldspar or quartz minerals. Background technique [0002] At present, there are three methods for removing iron minerals on the surface of feldspar and quartz concentrate at home and abroad: flotation to remove iron minerals, magnetic separation to remove iron minerals and pickling to remove iron minerals. Flotation method to remove iron minerals: Flotation method is a common method to remove iron minerals on the surface of feldspar or quartz concentrate. Since iron minerals are adsorbed on the surface of feldspar or quartz concentrate, during the flotation process, collectors are collected on the surface of iron minerals, thereby bringing out a large amount of feldspar or quartz concentrate, causing feldspar or quartz concentrate to enter Foam product, lost in ferrous mineral impurities. At present, when the flotation method...
