Problems solved by technology

[0003] The invention provides a new type of foaming agent for collecting and collecting copper ore in alpine regions and its application, aiming at the problem that the foaming agent for collecting and collecting copper ores in alpine regions is easy to crystallize in winter, resulting in low production indicators. Provides a new type of combined collecting foaming agent that does not crystallize in low temperature environment and can improve the production index of the dressing plant

Embodiment 1

[0013] Low temperature crystallization experiment

[0014] 2 parts of thiazonitrile ester, 1 part of butyl ammonium black medicine, 0.25 part of diesel oil, 0.5 part of ethanol, 1 part of 43# yellow cyanate. Discovery of crystallization.

Embodiment 2

[0016] Low temperature crystallization experiment

[0017] 5 parts of thiazonitrile ester, 2 parts of butyl ammonium black medicine, 0.5 part of diesel oil, 0.75 part of ethanol, 2 parts of 43# yellow cyanate. Discovery of crystallization.

Embodiment 3

[0019] A copper beneficiation plant in Sunan, Gansu:

[0020] The altitude of this place is more than 3,000 meters, the average temperature of the mine is 4°C, and the extreme temperature in winter is -35°C, and the dressing plant is in production all year round. The grade of copper raw ore is 0.62%. Before the use of new agents, the crystallization of conventional ester collecting foaming agents was relatively serious, which brought extreme inconvenience to the production of the dressing plant, not only high production costs, but also affected the indicators. On the basis of this background and small-scale experiments in the laboratory, a 30-day industrial experiment was carried out.

[0021] The present invention chooses 2 parts of thiazonitrile ester, 1 part of butyl ammonium black medicine, 0.25 part of diesel oil, 0.5 part of ethanol, and 1 part of 43# yellow cyanate.

[0022] The copper ore is wet-ground to a fineness of -0.074mm, accounting for 70%, the grinding concen...

Abstract

The invention discloses a novel combined collecting foaming agent for copper ore grading in a high and cold area and application of the novel combined collecting foaming agent. The novel combined collecting foaming agent is characterized by being prepared from the following components in parts by weight: 2-5 parts of cyanoethyl diethyl dithionocarbamate, 1-2 parts of ammonium dibutyl dithiophosphate, 0.25-0.5 part of diesel oil, 0.5-0.75 part of ethyl alcohol, and 1-2 parts of 43# yellow hydrocyanic ester. The problems that in the production process of a copper mine in the high and cold area in winter, the outdoor air temperature reaches minus 20-minus 30 DEG C or below, an ester collecting agent used currently is prone to being crystallized due to the high melting point, thus inconvenience is brought to production, and the production index is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of collecting and foaming agent for sorting copper ore, in particular to a novel combined collecting and foaming agent for sorting copper ore in alpine regions and its application. Background technique [0002] In the alpine region, due to the low temperature in winter (some places reach minus 20°C, referring to the storage temperature of chemicals), this has a great impact on the mining enterprises that produce in winter: 1. The workshop area and storage yard during production The temperature of ore and production water is low, which leads to poor mineralization of copper ore in the production process of the beneficiation plant, which affects the indicators; Ester-105, a common copper-selecting reagent, gradually crystallizes at room temperature below 23°C, which brings inconvenience to the production of the dressing plant. Therefore, in the production process, the agent needs to be pre-heated before use. ...
