Embodiment 1

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

[0027] (2) After pulping, add 750 g / t of collector N,N'-difatty acyl ethylenediamine sodium dipropionate at room temperature 13°C and natural pulp pH (pH=6.63), and stir for 2 minutes. Flotation, the flotation time is 3min. After the flotation, dry and weigh the foam product, namely the concentrate, and the tailings, the product in the tank, respectively, and take samples to test the grade, and calculate the recovery rate, among which the Zn grade in the flotation concentrate is 51.90%, and the recovery rate can reach 84.76%.

Embodiment 2

[0029] (1) The hemimorphite and quartz are configured into a mixed ore sample according to a mass ratio of 3:17, and 5g of the ore sample is weighed and put into a flotation cell and deionized water is added, wherein the mass ratio of the deionized water to the ore sample is 5:1; using a hanging tank flotation machine, under the condition of 1992r / min, stirring and pulping for 2min;

[0030] (2) After pulping, add collector N,N'-difatty acyl ethylenediamine dipropionate 900g / t under the condition of room temperature 13°C and natural pulp pH (pH=6.63), and stir for 2 minutes. Flotation, the flotation time is 3min. After the flotation, dry and weigh the foam product, namely the concentrate, and the tailings, the product in the tank, respectively, and take samples to test the grade, and calculate the recovery rate, among which the Zn grade in the flotation concentrate is 49.45%, and the recovery rate can reach 88.03%.

Embodiment 3

[0032] (1) The hemimorphite and quartz are configured into a mixed ore sample according to a mass ratio of 3:17, and 5g of the ore sample is weighed and put into a flotation cell and deionized water is added, wherein the mass ratio of the deionized water to the ore sample is 5:1; use the hanging tank flotation machine, under the condition of 1992r / min, stir and adjust the pulp for 2 minutes; add NaOH solution with a concentration of 1mol / L to the pulp to adjust the pH value of the pulp to 7.71, and then adjust the pulp for 2 minutes;

[0033] (2) After pulping, under the conditions of room temperature 13°C and pulp pH 7.71, add collector N,N′-difatty acyl ethylenediamine sodium dipropionate 900g / t, stir for 2min and then carry out flotation. The selected time is 3 minutes. After the flotation, dry and weigh the foam product, namely the concentrate, and the tailings, the product in the tank, respectively, and take samples to test the grade, and calculate the recovery rate, amon...

Abstract

The invention relates to a method for purifying hemimorphite from quartz through flotation, in particular to a hemimorphite and quartz flotation separation method, and belongs to the technical field of mineral flotation separation in the field of mineral processing engineering. According to the method for purifying the hemimorphite from the quartz through flotation, a to-be-processed hemimorphiteand quartz mixed ore sample is mixed with deionized water, a collecting agent is added in ore pulp stirred to be uniform, wherein the use quantity of the collecting agent ranges from 750 g / t to 900 g / t; and flotation is conducted after the ore pulp with the added collecting agent is stirred to be uniform, wherein the collecting agent is N, N'-difatty acyl thylenediamine dipropionate. The method for purifying the hemimorphite from the quartz through flotation is simple in technological process, simple in agent regime and convenient to operate and has good industrial feasibility prospects.

Description

technical field [0001] The invention relates to a method for flotation purification of hemimorphite from quartz, in particular to a flotation separation method of hemimorphite and quartz, and belongs to the technical field of mineral flotation separation in the field of mineral processing engineering. Background technique [0002] Zinc is the fourth "common" metal, after iron, aluminum and copper. Due to its suitable mechanical properties and anti-corrosion properties, zinc is widely used in automobile, construction, shipbuilding, light industry and other industries, especially in modern industrial battery manufacturing, which has an irreplaceable position. Since entering the 21st century, with the rapid growth of my country's economy, the demand for zinc resources is also increasing. my country has become the world's largest zinc producer and zinc resource consumer. From 2006 to 2014, my country's zinc metal production increased by nearly 85%. In 2014, my country's zinc c...
