Abstract

According to the operation practices of concentrating plants, the production of bulk copper-lead concentrates with their subsequent selective separation is the most often used process design in polymetallic ore processing. During selective separation of bulk concentrates, lead minerals are depressed using various oxidizing agents, such as potassium permanganate, chromium salts, etc. This work provides the results of laboratory studies on the possibility of using iron-containing reagents as depressants for lead minerals in the separation of copperlead concentrates. For the research, a copper-lead concentrate process sample of the Maleevskoe deposit ore (Kazakhstan) and two ironcontaining reagent samples were used. The material composition of the samples was studied. The mass fractions in the copper-lead concentrate were 16.84 % of lead, 2.46 % of zinc, 25.43 % of copper, and 22.06% of iron. The analysis of variance demonstrated that the bulk of the metals in the concentrate were localized in the size class of –0.044 mm. According to the results of the X-ray phase analysis, iron was presented in the form of goethite and hematite in sample No. 1 of the iron-containing reagent and in the form of magnetite in sample No. 2. A comparison was carried out using a bichromate slurry heated to 40–45 °С and the sulfite technology. The flotation process using iron-containing reagents included preliminary desorption with three washing cycles, rougher and scavenger copper flotation cycles with the slurry pH of 5.6 to 5.8, and two cleaner flotation cycles for the copper concentrate. It was established that, when using the sulfite technology, at the optimum flow rate of 2 kg/t, iron-containing reagent No. 2 enabled eliminating the high consumption of sodium sulfite (8 kg/t) and iron sulfate (5 kg/t) from the selection process without affecting the process parameters of flotation concentration.
The research was completed with the financial support of the Science Committee of the Ministry of Education and Science of the Republic of Kazakhstan under grant No. AP05132112.
