Description
One, technical field
The present invention relates to a kind of method of vulcanizing-flotation Combined Treatment zinc kiln slag, a kind ofly specifically carry out vulcanizing treatment with microwave, adopt the valuable metal element in the mode separation of Zinc kiln slag of flotation then, obtain the method for copper-lead bulk concentrate, zinc concentrate and iron ore concentrate.Belong to choosing-smelting Combined Treatment technical field.
Two, technical background
The residue that zinc kiln slag is zine-smelting plant's zinc hydrometallurgy leached mud after rotary kiln evaporation is handled belongs to the secondary smelting slag, and it contains valuable metal elements such as a certain amount of iron and part zinc, copper, silver, has bigger recovery value.But because its thing phase composition is extremely complicated, cause the valuable metal element in the zinc kiln slag to be difficult to reclaim, cause the waste of resource.Known in the past zinc kiln slag treatment technology shows, is mostly to adopt more than 1200 ℃ temperature to carry out the processing of thermal process route, in case add vulcanizing agent or chlorinating agent, the problem of inevitably bringing sulfide or chloride environmental pollution into; Zinc kiln slag is to belong to a kind of oxide ore, oxide ore directly carries out the known document of FLOTATION SEPARATION and (opens deep, Qiu Yueqin, Tang Yun etc. STUDY ON MINERAL TECHNOLOGY OF ZINC OXIDE. the journal .2000 of Guizhou University of Technology, 29 (6): 49～53) show that the lead-zinc thing has the characteristics of difficult choosing.
Three, summary of the invention
The present invention provides a kind of method of vulcanizing-flotation Combined Treatment zinc kiln slag, adopt broken mill, microwave vulcanization and floatation process, comprehensive copper-lead bulk concentrate, zinc concentrate and the iron ore concentrate of reclaiming from zinc kiln slag, the mode that the present invention adopts cryogenic vulcanization and floatation process to combine, reach and reduced energy consumption and the sulphide flotation performance is good, the vulcanizing agent addition is few, reduced environmental pollution and changed the purpose of mineral surfaces activity.
Fig. 1 is seen in patent technological process of the present invention, and the invention step is as follows:
1) the raw material zinc kiln slag is carried out dry milling to the account for 30～50wt% of granularity, add the elemental sulfur of 3-5wt%, fully behind the mixing, obtain sulphur matter mixture for-0.074mm;
2) sulphur matter mixture is carried out the heating using microwave sulfuration, vulcanization process condition is: microwave vulcanization 5-8min, microwave power are 400～850W, and curing temperature is 250～500 ℃;
3) product after the microwave vulcanization is carried out wet grinding, the ore pulp concentration expressed in percentage by weight is 50-60%, and granularity is milled to-and 0.074mm accounts for 60～75wt%;
4) mixture behind the wet grinding is carried out flotation, the flotation concrete steps are as follows: at first carry out the bulk flotation of copper-lead, add and adjust agent sodium metasilicate 90～110g/t, mix 2～8min, inhibitor carboxymethyl cellulose (CMC) 45～55g/t mixes 2～8min, collecting agent hydroximic acid 700～900g/t, mix 2～8min, foaming agent 2
#Oil 30～45g/t behind mixing 1～5min, roughly selects 5min, adds hydroximic acid 150～250g/t again, mixes 2～3min, adds 2
#Oil 30～45g/t mixes 2～3min, scans 4min, finishes the bulk flotation of copper-lead, obtains copper-lead bulk concentrate and mine tailing; In second step, mine tailing carries out the flotation of zinc mineral, adds activator vulcanized sodium 1300～1500g/t, mixes 2～3min, adds collecting agent mixed amine (RNH
2) 450～550g/t, mix 2～3min, roughly select 5min, add vulcanized sodium 400～500g/t again, mix 2～3min, add mixed amine 200～300g/t, mix 2～3min, scan 4min, finish the flotation of zinc mineral, obtain zinc concentrate and iron ore concentrate.
Compare advantage and good effect that the present invention has with known technology:
1) the microwave vulcanization zinc kiln slag is to carry out under cryogenic conditions, and temperature is 250～500 ℃, can reduce additive elemental sulfur (S) volatilization contaminated environment;
2) have the reducing atmosphere of microwave vulcanization zinc kiln slag: because zinc kiln slag contains a certain amount of reducing agent carbon, and carbon is preferential and system in the oxygen combination, stoped additive S and oxygen combination, further prevent elemental sulfur (S) contaminated environment;
3) additive sulfur (S) has improved the activity of zinc kiln slag mineral surfaces under the effect of microwave, makes that the more original oxide ore of mineral after the sulfuration is easy to FLOTATION SEPARATION.And (chemical formula is CuFeS to additive sulfur (S) than pyrite
2) 0.5 sulphur (S) is provided more;
4) adopted cryogenic vulcanization-flotation selecting smelting combination mode to handle zinc kiln slag, obtain copper-lead bulk concentrate, zinc concentrate and iron ore concentrate.Known technology was compared in the past, process reform of the present invention mineral surfaces activity and reduced energy consumption, have the good and energy-saving significance of flotation performance.
