Embodiment 1

[0026] (1) smithsonite and quartz with a mass ratio of 3:17 are configured into a mixed ore sample, and 5g of the ore sample is weighed and put into a flotation cell, and then deionized water is added, wherein the amount of ore sample and deionized water The mass ratio is 1:5; using a hanging tank flotation machine, under the condition of 1992r / min, stirring and pulping for 2min;

[0027] (2) After pulping, add 1mol / L sodium carbonate solution as a pH adjuster at room temperature at 13°C, adjust the pH of the pulp to 10.82, stir for 2 minutes, and then add 300g / t of N,N'-difatty acyl Sodium ethylenediamine dipropionate was used as a collector, and after stirring for 2 minutes, flotation was carried out, and the flotation time was 3 minutes. After the flotation, dry and weigh the foam product, which is the concentrate, and the tailings, which is the product in the tank, and take samples to test the grade and calculate the recovery rate. The Zn grade in the flotation concentrate...

Abstract

The invention relates to a method for flotation and silica removing of bonamite zinc oxide ore, in particular to a bonamite and quartz flotation separation method, and belongs to the technical field of mineral flotation separation in the field of mineral process engineering. According to the method for flotation and silica removing of bonamite zinc oxide ore, a to-be-treated mixed ore sample of bonamite and quartz and deionized water are mixed, and the mass ratio of the deionized water to the ore sample is 3-5:1; sodium carbonate is adopted as a pH value adjusting agent firstly, a collecting agent is added in evenly-stirred pulp, and the usage amount of the collecting agent is 300-360 g / t; and the pulp in which the collecting agent is subjected to flotation after being evenly stirred. Thecollecting agent is N,N'-bi-fatty acyl group quadrol bi-sodium propionate. According to the provided method for flotation and silica removing of bonamite, the regime of agent is simple, the technologyprocess is simple, operation is convenient, and good industrial feasible prospects are achieved.

Description

technical field [0001] The invention relates to a method for flotation desiliconization of smithsonite-type zinc oxide ore, in particular to a flotation separation method for smithsonite and quartz, and belongs to the technical field of mineral flotation separation in the field of mineral processing engineering. Background technique [0002] The consumption of zinc resources ranks third among non-ferrous metals and fourth among metals. Zinc is relatively stable under dry external conditions, but it is easy to form a dense zinc carbonate film on the surface under wet conditions, so it can be used to treat the surface of other materials. Most zinc metals are currently used in the galvanizing industry. In addition, zinc is also widely used in rubber, batteries, shielding materials, pigments, printing, paint and other industries. In recent years, with the rapid growth of China's economy, my country's demand for zinc resources has also increased. In 2014, my country's zinc con...
