The invention discloses a flotation inhibitor for copper oxide minerals and a flotation method for copper oxide or copper oxide cobalt ores, and belongs to the technical field of mineral separation. The copper oxide mineral flotation inhibitor comprises sulphide salt, dithiocar-bamate and cysteine, is used in a copper oxide or copper oxide cobalt ore reverse flotation system, and can realize high-selectivity inhibition on copper oxide minerals such as malachite so as to ensure that calcium magnesium carbonate gangue minerals are efficiently collected by a fatty acid collector, so that the flotation efficiency of the copper oxide minerals is improved. Therefore, the calcium-magnesium gangue minerals can be directly removed through reverse flotation, the recovery rate of the calcium-magnesium gangue minerals in foam products is 90% or above, the leaching acid consumption of copper oxide or copper oxide cobalt ore concentrate is greatly reduced, and the production cost is greatly reduced.

The present application relates to a kind of mineral material composite cobalt-based catalyst, preparation method and its application.The mineral material composite cobalt-based catalyst includes mineral material and cobalt, mineral material is selected from one or more than two combinations of malachite, monazite, manganese ore, mullite, attapulgite, copper ore, iron ore and ilmenite, and the content of cobalt is 25~75% by mass of element, the valence of cobalt is mainly metal oxide, the ratio of Co 3+ / Co 2+ In metal oxide is 0.2~0.8.The mineral material composite cobalt-based catalyst of the present application is simple in preparation method, low in cost, can effectively catalyze oxidation of low-carbon alkane organic volatile matter, and still can maintain higher low-carbon alkane conversion rate under water vapor condition.

The invention discloses an efficient malachite flotation recovery method based on mineral surface low-temperature hydrogen plasma modification, and belongs to the technical field of malachite beneficiation and purification processes. The efficient malachite flotation recovery method comprises the following steps: (1) performing low-temperature hydrogen plasma pretreatment on malachite raw ore at room temperature; (2) adding deionized water into the malachite raw ore subjected to low-temperature hydrogen plasma treatment for size mixing; (3) performing direct flotation to separate malachite and quartz; and (4) the foam product is dried, and malachite concentrate obtained after flotation separation and purification is obtained. According to the method, the surface of the malachite is treated through the low-temperature hydrogen plasma technology, the good flotation recovery effect is achieved, the collecting efficiency of xanthate on the malachite is remarkably improved, the dependence of traditional copper oxide ore flotation on a vulcanizing agent is broken through, and a new strengthening way is provided for malachite flotation.
