Problems solved by technology

[0003] For the recovery of molybdenum from copper-molybdenum ores, a lot of research work and practice have been carried out at home and abroad, most of which use the separation technology of copper-inhibiting and floating molybdenum, but the copper-inhibiting inhibitors and floating molybdenum collectors used are mostly single drugs , such as sodium sulfide, sodium cyanide, kerosene, etc. However, when a single drug is used, the dosage needs to be large to separate completely, which causes the COD of the pharmaceutical wastewater to exceed the standard and brings environmental problems

Abstract

The invention relates to the technical field of non-ferrous metal processing, in particular to a copper molybdenum separation flotation agent and a using method thereof. The copper molybdenum separation flotation agent comprises inhibitor for inhibiting copper mineral and collecting agent for collecting molybdenum mineral, wherein the inhibitor comprises, by weight, 3 to 5 parts of sodium carbonate, 3 to 5 parts of sulfate, 10 to 15 parts of copper compounds, 15 to 20 parts of sulfide salt, and 15 to 20 parts of hydrosulphide salt; the collecting agent comprises, by weight, 1 to 3 parts of oleic acid, 15 to 25 parts of butyl octyl oleate, and 40 to 50 parts of oil pyrolysis products. The copper molybdenum separation flotation agent and the using method thereof reduce usage amount of the agent, can achieve a certain degree of degradation in waste water if the agents are mutually matched, and thus are more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal beneficiation, in particular to a copper-molybdenum separation flotation agent and a use method thereof. Background technique [0002] Molybdenum is an element that is rarely distributed in nature. The average content in the earth's crust is about 0.001%. The United States has the most abundant molybdenum resources in the world, followed by Canada and Chile. my country's molybdenum resources are relatively rich, but now except molybdenite In addition to forming molybdenum deposits alone, they widely coexist with other sulfide beds to form polymetallic deposits, such as copper-molybdenum-sulfur deposits. [0003] For the recovery of molybdenum from copper-molybdenum ores, a lot of research work and practice have been carried out at home and abroad, most of which use the separation technology of copper-inhibiting and floating molybdenum, but the copper-inhibiting inhibitors and floating mol...
