Cleaning agent for filter cloth for copper concentrate filtering

Abstract

The invention relates to a cleaning agent for filter cloth for copper concentrate filtering. Residue matters and plugging particles of the surface of the filter cloth are analyzed, so that two kinds of inorganic acids, namely acetic acid and hydrofluoric acid which have a mutually-promoting role on a cleaning effect are determined at first. Then, in order that reaction of acids and silk threads or particle matters in fibers of the filter cloth is more complete, a nonionic penetrating agent JFC-E (a kind of fatty alcohol-polyoxyethylene ether) is added in acids, and therefore the aqueous cleaning agent with a significant cleaning effect is prepared. The acetic acid concentration of the cleaning agent is 9-15 percent, the hydrofluoric acid concentration is 0.5-1.5 percent, and the JFC-E concentration is 0.1-0.3 percent. As the two kinds of inorganic acids with the mutually-promoting role are adopted to react with the residue matters of the surface of the filter cloth, particles on the surface of the filter cloth can be effectively removed. Meanwhile, as the nonionic penetrating agent JFC-E is added, the cleaning agent can penetrate among the silk threads or fibers of the filter cloth to react with the plugging particles, the cleaning effect is greatly increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of filter cloth cleaning and regeneration, in particular to a cleaning agent for filter cloth used for filtering copper concentrate. Background technique [0002] Copper-molybdenum deposits mainly composed of copper and accompanied by molybdenum often exist in the porphyry copper ore type. The beneficiation of porphyry copper ore has a history of several decades in my country. Commonly used beneficiation method. In porphyry copper-molybdenum deposits, copper, molybdenum, and sulfur are generally three minerals that coexist. With the large-scale development and utilization of porphyry-type copper-molybdenum ores in recent years, the ores that are easy to mine and smelt are gradually exhausted. And with the transformation of my country's economic development mode, the requirements for the utilization rate of ore are higher, so that in order to make full use of the ore, the ore particles are finer and smaller ...
