Embodiment 1
[0063] see Figure 5 Shown is a process flow diagram of a method for processing copper-cobalt sulfide ore. The copper grade in a copper-cobalt ore is 5.39wt%, and the cobalt grade is 0.059wt%.
[0064] (1) Grinding the copper-cobalt sulfide ore with a ball mill, the obtained grinding fines have a particle size not higher than 0.074mm and account for 65%;
[0065] (2) The ground fine material is mixed with butyl xanthate and terpineol oil to carry out one stage of flotation, so as to obtain one stage of flotation concentrate and one stage of flotation tailings, wherein, based on 1t of copper-cobalt ore, butyl xanthate The dosage is 80g, the dosage of terpineol oil is 40g, and the one-stage flotation time is 5min;
[0066] (3) Mix the first-stage flotation tailings with butyl xanth and terpineol oil for second-stage flotation, so as to obtain the second-stage flotation concentrate and the second-stage flotation tailings, based on 1t of copper-cobalt ore, butyl xanthate The co...

Abstract
The invention discloses a method for processingcoppersulfidecobalt ore. The method comprises the following steps of (1) carrying out ore grindingprocessing on the coppersulfidecobalt ore to obtain a fine grinding material; (2) mixing the fine grinding material, a collecting agent and terpenic oil and carrying out first-stage flotation, and acquiring first-stage flotation concentrate and first-stage flotation tailings, wherein the collecting agent is butyl xanthate and / or ammoniumdibutyl dithiophosphate; (3) mixing the first-stage flotation tailings, the collecting agent and the terpenicoil to carry out second-stage flotation, and acquiring second-stage flotation concentrate and second-stage flotation tailings; (4) carrying out first-stage concentration on the first-stage flotationconcentrate and the second-stage flotation concentrate to obtain first-stage concentration concentrate and first-stage concentration tailings; (5) carrying out second-stage concentration on the first-stage concentration concentrate to obtain second-stage concentration concentrate and second-stage concentration tailings; and (6) carrying out third-stage concentration on the second-stage concentration concentrate to obtain third-stage concentration concentrate and third-stage concentration tailings. By adopting the method,copper and cobalt elements can be efficiently recycled, a process is simple, a comprehensive utilization rate of mineral resources can be increased, and economic benefits of enterprises can be increased too.
Description
technical field [0001] The invention belongs to the field of mineral processing, and in particular relates to a method for processing copper-cobalt sulfide ore. Background technique [0002] Cobalt mainly occurs in other minerals in the form of isomorphism or inclusions. About 60% of the world's cobalt ore output comes from copper-cobalt ore, and copper-cobalt ore is one of the important sources of cobalt. According to the current reports, flotation is the main method for recovering sulfur copper cobalt ore. Mainly mixed flotation and priority flotation. The common problem is that the cobalt recovery rate is low and the process is complicated. Efficient and comprehensive recovery of valuable metals copper and cobalt in copper-cobalt ore is of great significance for improving the comprehensive utilization rate of mineral resources and greatly increasing the economic benefits of enterprises. Contents of the invention [0003] The present invention aims to solve one of the...
