Embodiment 1

[0022] Copper-cobalt oxide ore with Cu 3.88% and Co 0.14% in a foreign copper mine, the original ore was crushed, and the ore was ground to -0.074mm, accounting for 71%, and the flotation was carried out according to the amount of reagents listed in Table 1 to obtain copper oxide concentrate and flotation Tailings; the flotation tailings are subjected to magnetic separation at the magnetic field strength shown in Table 2 to obtain cobalt concentrate and magnetic separation tailings, and the results are shown in Table 3. The final copper oxide concentrate contains 33.45% Cu, with a recovery rate of 85.59%, and the cobalt concentrate contains 0.88% Co, with a recovery rate of 76.30%.

Abstract

The invention relates to a beneficiation method for copper oxide cobalt ores. The beneficiation method is characterized by comprising the following steps of 1, ore grinding, i.e. crushing and grinding raw ores; 2, copper oxide flotation, i.e. adding sodium sulfide, a collecting agent butyl xanthate and a foaming agent terpenic oil in the primary roughing process, adding sodium sulfide, butyl xanthate and terpenic oil in the primary scavenging process, adding sodium sulfide, butyl xanthate and terpenic oil in the secondary scavenging process and carrying out secondary blank concentration to obtain copper oxide concentrates and flotation tailings; and 3, magnetic separation, i.e. carrying out primary roughing magnetic separation on the flotation tailings to obtain cobalt rough concentrates and magnetic separation tailings and carrying out secondary concentration magnetic separation on the cobalt rough concentrates to obtain cobalt concentrates and magnetic separation tailings. The invention provides the beneficiation method for the copper oxide cobalt ores, which reduces cost and pollution. The method disclosed by the invention is suitable for the copper oxide cobalt ores comprising copper oxide ores, copper oxide cobalt ores and cobaltous oxide minerals.

Description

technical field [0001] The invention relates to a beneficiation method of copper-cobalt oxide ore. Background technique [0002] Copper is an important metal indispensable to modern industry, and also an important strategic mineral related to the national economy and people's livelihood. Cobalt is an important raw material additive in the magnetic material industry. It can effectively improve the high temperature resistance and anti-aging effects of the finished magnetic material in the process. It is widely used in machinery, electricity, electronics, construction, military and other fields. [0003] The shortage of copper metal mineral resources in my country is very serious, which is extremely disproportionate to my country's status as the largest copper production and consumption country. my country's cobalt resources are also quite scarce. According to statistics, the current cumulative proven reserves are 583,000 tons, and China produces about 700 tons of cobalt every...
