Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of sulfur concentrate removal impurity purification purification flotation process, solve the problems such as the utilization rate of existing sulfuric acid plant slag iron is low, technical index is low, economic benefit is poor; Iron, gold and non-ferrous metals, providing enterprises with a simple and easy process, high technical indicators, good economic benefits, output of high-purity iron sulfide concentrate to produce acid, so that the grade of sulfuric acid slag iron can directly meet the requirements of ironmaking, It becomes a new process of iron concentrate powder, which will also change the history of sulfuric acid plants that only produce sulfuric acid. It will also produce iron concentrate powder and gold at the same time, and can also recycle the non-ferrous metals contained in part of the sulfur concentrate , will make 100% utilization of sulfuric acid slag, this process has great practicality and economic benefits;

Abstract

The present invention relates to an impurity-removing purification floatation process for sulfur concentrate, belonging to the metallurgical chemical field. Its technical core is characterized by changing the traditional mode of using sulfuric acid to burn slag and separate iron into the mode of floating and purifying iron sulfide as raw material for producing sulfuric acid, using produced high-grade iron sulfide concentrate to make acid and making the slag-burned iron grade be directly reached to requirement for smelting iron and can obtain refined iron powder, so that 100% of burned slag can be utilized. Said process has two contents, one is to cyanide tail slay of gold concentrate which is one of sulfuric acid raw material and remove impurity and another is to purify sulfur concentrate. Said invention can make vitriol plant not only produce sulfuric acid, but also produce iron concentrate powder and gold.

Description

technical field [0001] The invention relates to a flotation process for removing impurities and purifying sulfur concentrates. The process mainly involves the utilization of sulfur, iron and gold in sulfur concentrates and the technical problems of comprehensive recovery of copper, lead and zinc contained in some raw materials. Background technique [0002] At present, the utilization status of sulfuric acid slag at home and abroad is quite different. The utilization rate of iron in domestic sulfuric acid slag is not high. Valuable components such as non-ferrous metals have not been utilized; now, the raw material for general sulfuric acid production is sulfur concentrate, that is, iron sulfide concentrate, which is produced from pyrite mines, gold mines and non-ferrous metal mines, and gold mines. Sulfur concentrate is the cyanidation tailings of flotation gold concentrate; while the sulfur grade of sulfur concentrate is generally 30% to 40%, and the sulfur concentrate with...
