The strong magnetic roughing concentrate is then subjected to strong magnetic concentration with a magnetic separator to obtain strong magnetic concentrated concentrate and strong magnetic tailings. The strong magnetic roughing tailings are the final magnetic tailings. Use a high gradient magnetic separator with 0.8-1.2T magnetic field for strong magnetic roughing to obtain strong magnetic roughing concentrate and strong magnetic roughing tailings. Copper-cobalt ore flotation-magnetic separation combined process is suitable for processing oxidized ore with more magnetic substances and can effectively improve the grade of magnetic separation concentrate.įlotation-Magnetic Separation Combined Process Flowįirst, grind the copper-cobalt oxide ore flotation tailings with a mill to -0.074mm, accounting for 70-90%, and make a slurry with a 10-40% concentration. Because cobalt has weak magnetism, we can recover it with magnetic separation. ![]() When the composition of copper-cobalt ore is complex, single flotation cannot effectively recover cobalt. Flotation-Magnetic Separation Combined Process Separate the foam after separation and flotation of copper and cobalt twice to get copper concentrate. Add inhibitors and collectors successively, carry out copper-cobalt separation flotation, and obtain cobalt after one roughing and sweeping concentrate. Add inhibitors to the mixed flotation foam, and get the copper-cobalt mixed concentrate after three times of beneficiation. Sequentially add collectors and foaming agents to the ore pulp after grinding, carry out copper-cobalt mixed flotation roughing, and then obtain tailings after two sweeps. Add a certain amount of regulator during the grinding process to adjust the pH value of the pulp to the range of 9-10. The specific process is that the raw copper-cobalt ore is ground. It can recover low-grade and complex fine-grained copper and cobalt minerals, reduce the difficulty of separating copper and cobalt minerals, and improve the quality and recovery rate of copper and cobalt concentrates.Ĭopper-cobalt ore flotation is to mix and flotation of copper-cobalt to obtain a mixed concentrate and then separate copper and cobalt to get copper concentrate and cobalt concentrate. The flotation process is easy to operate and highly controllable, and it is also suitable for copper-cobalt ore with low grade and fine particle size. What Are The Beneficiation Processes of Copper-cobalt Ore? 1. The commonly used separation methods include flotation, flotation-magnetic separation combination, and leaching process. It is an important strategic material.Ĭopper-cobalt ore is a kind of cobalt ore that can be used to separate and extract cobalt. People wide used in aerospace, machinery manufacturing, electrical appliances, and chemical industries. It is an important raw material for manufacturing heat-resistant, anti-corrosion, and hard alloys. Low Intensity Dry Drum Magnetic SeparatorĪgitating chute is a new kind of gold and chip gold extraction machine…….Ĭobalt is a hard magnetic metal with a high melting point and good stability.Crispin Mwenda, a 63-year-old local resident who lost his home, said evictees were not allowed to retain a copy on an agreement protocol COMMUS had given them. During the first wave of evictions in 2016, 56 households were affected. Amnesty International compiled the report with DRC-based organisation Initiative pour la Bonne Gouvernance et les Droits Humains by interviewing more than 130 people at six different mining projects in Kolweziin the southern province of Lualaba.Ĭampaigne Minière de Musonoie Global SAS (COMMUS), a joint venture between Chinese company Zijin Mining Group and the DRC’s state mining company Générale des Carrières et des Mines (Gécamines), run the mines in the Kolwezi area. Residents have been forcibly evicted from their homes and subjected to human rights abuses such as sexual assault, arson and beatings. The expansion of cobalt and copper mines in the Democratic Republic of Congo (DRC) is “wrecking lives”, according to a report published by Amnesty International on Tuesday.

Artisanal miners dig for cobalt and copper at the Shabara artisanal mine near Kolwezi, Democratic Republic of Congo, in October 2022.
