Abstract

The invention discloses a method for recovering Ni-Co-Cu from Ni polymetallic ores. The method comprises the steps of (1) conducting ore grinding treatment on the Ni polymetallic ores to obtain ore grinding fines; (2) mixing the ore grinding fines with sodium carboxymethyl cellulose, sodium carbonate, sodium p-octadecyl toluene sulfonate, diethylenetria, sodium n-butylxanthate and terpenic oil, and conducting first-stage flotation to obtain first-stage flotation concentrates and first-stage flotation tailings; (3) mixing the first-stage flotation tailings with sodium carboxymethyl cellulose, sodium p-octadecyl toluene sulfonate, diethylenetria, sodium n-butylxanthate and terpenic oil, and conducting second-stage flotation to obtain second-stage flotation concentrates and second-stage flotation tailings; (4) mixing the first-stage flotation concentrates and the second-stage flotation concentrates with sodium carboxymethyl cellulose, sodium carbonate, sodium p-octadecyl toluene sulfonateand diethylenetria, and conducting first-stage cleaning to obtain first-stage cleaned concentrates and first-stage cleaned tailings; and (5) conducting second-stage cleaning on the first-stage cleaned concentrates to obtain second-stage cleaned concentrates and second-stage cleaned tailings.

Description

technical field [0001] The invention belongs to the field of mineral processing, in particular to a method for recovering nickel-cobalt-copper from nickel polymetallic ore. Background technique [0002] Cobalt is a very important strategic element, known as "industrial monosodium glutamate", has the advantages of high melting point, good wear resistance, high mechanical strength, strong magnetism, etc., and is widely used in aviation, aerospace, machinery manufacturing, chemical industry and other industries department. With the rapid development of my country's economy, the demand for cobalt is increasing. Cobalt is mainly present in other minerals in the form of isomorphism. Nickel polymetallic ores generally contain associated valuable elements such as cobalt. However, the current process mainly considers the recovery of nickel and copper, and little attention is paid to the recovery of associated valuable elements cobalt, resulting in a waste of resources. [0003] Th...
