Abstract
The invention discloses a beneficiation method of high-oxidation-rate copper-molybdenum paragenic ore, which comprises the following steps: (1) crushing: crushing and screening raw ores by a crusher, and returning and crushing the raw ores with the grain size of +3mm until the grain sizes of all the raw ores reach the grade of-3 mm; (2) grinding: adding crushed-3 mm raw ore into raw ore grinding equipment to perform closed circuit grinding operation, and simultaneously adding 1000-3000 g/t of activating agent and 250-900 g/t of vulcanizing agent into a grinding machine to grind the raw ore to the content of 55-80% of-0.075 mm; (3) performing flotation roughing operation; (4) performing flotation scavenging operation; (5) flotation and fine selection operation; (6) and (5) performing strong magnetic separation. By adopting the method, the copper oxide minerals and the molybdenum oxide minerals in the copper-molybdenum paragenic ore with high oxidation rate can be subjected to beneficiation, enrichment and recovery to obtain high-quality qualified copper concentrate and a relatively enriched molybdenum middling, and the molybdenum middling can be used as a raw material for producing ammonium molybdate products by chemical wet leaching, so that molybdenum oxide resources in the ore can be recycled.
Description
Technical field
The present invention relates to the beneficiation enrichment technology field of cupric oxide molybdenum symbiotic ore, especially a kind of beneficiation method of high oxidation rate copper molybdenum symbiotic ore, the present invention is applicable to the beneficiation enrichment of various high oxidation rate cupric oxide molybdenum symbiotic ore.
Background technology
China's copper, molybdenum ore resource are very abundant, end for the end of the year 2014, and copper ore resource amount reaches 9,111 ten thousand tons, and Mo resource reserves reach 2,826 ten thousand tons, are the Dominant Mineral Resources of China.The principle that China is poor, easy first and difficult later after usually following getting rich first to the exploitation of mineral resources, along with the high speed development of modern industry, limited easily select copper sulfide, molybdenum ore resource peters out, remaining copper, molybdenum ore mostly are the ore resource of the higher very difficult enrichment of oxygenation efficiency.
The principle of the industrial cupric oxide ore for partial oxidation and the many foundations of oxidizing molybdenum ore " after first sulphur oxygen ", the copper sulfide in first flotation of ores and molybdenum sulfide, then the method for flotation after the oxide ore sulfuration in mine tailing is reclaimed it.
The copper molybdenum symbiotic ore of high oxidation rate, refer to that molybdenite and the chalcopyrite of symbiosis experienced by wind erosion, drench with rain in very long geological epoch, the top of Cu-Mo separation or selective oxidation after sunshine, molybdenum sulfide part or major part are oxidized to molybdine molybdite or molybdate ore, and copper sulfide part or major part are oxidized to secondary copper sulfide or cupric oxide ore.
Cupric oxide ore many employings floatation and chemical method are processed, floatation is the main method of process cupric oxide ore, be applicable to mineral composition simple, the uncomplicated cupric oxide ore of character, the focus of its research concentrates on the selection of the most efficient flotation reagents and the control of sulfidation; The cupric oxide ore that should not adopt floatation or adopt floatation process index poor, adopt chemical Treatment more, if publication number is 103128004A, publication date is a kind of method that the Chinese patent literature on June 5th, 2013 discloses copper sulfide molybdenum bulk concentrate floatation FLOTATION SEPARATION, it carries out according to the following steps: choosing of (1) copper molybdenum bulk concentrate floatation, sizes mixing; (2) in ore pulp, add adjustment inhibitor waterglass sequentially, the high efficiency selected inhibitor hydroxamic acid starch of copper, vulcanized sodium, molybdenum sulfide mineral collector kerosene, foaming agent 2# oil (terpenic oil) carries out molybdenum and roughly select operation, obtain molybdenum rough concentrate and molybdenum rougher tailings, rougher tailings adds kerosene and 2# oil to carry out molybdenum and scans, scanning number of times is 1 ~ 3 time, obtain molybdenum flotation tailing and be copper concentrate, scavenger concentrate order is back to last flotation operation; (3) molybdenum rough concentrate adds copper mineral inhibitor hydroxamic acid starch and vulcanized sodium, and concentration times is 5 ~ 9 times, obtains molybdenum concntrate, and molybdenum selected chats order is back to last flotation operation.The method is applicable to that disseminated grain size is thin, cupric is low, argillization is serious, ore structures and composition change greatly, the cupric oxide ore of the feature such as sulfuration is difficult.
Floatation and chemical method is adopted to process for molybdenum oxide ore as much, floatation is applicable to that mineral composition is simple, the uncomplicated molybdenum oxide ore based on molybdine molybdite of character, and the molybdenum oxide mineral that chemical method is applicable to the poor molybdine molybdite class mineral of flotation effect and exists with molybdic acid salt mineral forms such as molybdenum calcium ore deposit, wulfenite, molybdic acid iron ores, such ore carries out enrichment owing to can not adopt floatation to it, many directly employing chemical method wet-leachings, then output ammonium molybdate or molybdenum oxide product.This technique, due to Chemical Leaching direct without beneficiation enrichment, considerably increases the generation of the raw-material consumption such as soda acid and waste residue and waste liquid, adds production cost, reduce the productivity effect of enterprise, simultaneously easily brings severe contamination to environment.
Summary of the invention
Complicated for the mineral composition of the type high oxidation rate copper molybdenum symbiotic ore, copper molybdenum oxygenation efficiency is high and molybdenum mainly causes being difficult to the technical barrier by floatation process enrichment with the existence of molybdenum calcium ore deposit form, the present invention proposes a kind of beneficiation method for the type high oxidation rate copper molybdenum symbiotic ore, adopt this method, all beneficiation enrichment recovery can be carried out to the copper oxide mineral in the type high oxidation rate copper molybdenum symbiotic ore and molybdenum oxide mineral, obtain the molybdenum chats of the qualified copper concentrate enrichment relative to of high-quality, this molybdenum chats can be used as wet chemical and leaches the raw material producing ammonium molybdate product, the molybdenum oxide resource in ore is made to be recycled utilization.
The present invention realizes by adopting following technical proposals:
A beneficiation method for high oxidation rate copper molybdenum symbiotic ore, is characterized in that step is as follows:
(1) broken: adopt disintegrating machine by crushing raw ore and screening ,+3mm grade raw ore returns fragmentation, until all original ore sizes reach-3mm rank;
(2) ore grinding: to the good-3mm raw ore of fragmentation, add in raw ore grinding attachment and carry out closed circuit grinding operation, adds activator 1000 ~ 3000g/t, vulcanizing agent 250 ~ 900g/t simultaneously, raw ore is milled to-0.075mm content 55 ~ 80% in grinding machine;
(3) roughing flotation operation;
(4) operation is scanned in flotation;
(5) the selected operation of flotation;
