Flotation is the main beneficiation method for obtaining powdered antimony concentrate, and flotation is included in almost all beneficiation processes. The types of ore used for treatment are: mono-sulfurized antimony ore, sulfurized-oxidized mixed antimony ore, tungsten- niobium- gold polymetallic sulfide ore, antimony- arsenic gold sulfide ore, tin , lead , antimony, zinc polymetallic sulfide ore, antimony, lead. , zinc, mercury polymetallic sulphide ore, arsenic, antimony, gold poly-gold sulfide ore, etc., now the tin ore single ore of the tin mine and the processing of tin, zinc, lead and antimony polymetallic ore in Guangxi Dachang as an example to illustrate a single Flotation process of antimony sulfide ore and antimony sulfide. The ore dressing process of the tin mine south mine is the hand-selective-heavy medium selection-flotation process. The production indexes of the whole process and the flotation conditions used are listed in Tables 1 and 2. Table 1 Example of production index of tin mine south plant (%) Sorting operation Operating rate Ore grade Concentrated concentrate grade Tailings grade Recovery rate Hand selection 33.3 2.25 7.8 0.12 95.95 Heavy medium 6.6 1.58 2.65 0.18 95.11 Flotation 60.1 3.19 47.58 0.21 93.97 Total or average 100.0 2.68 19.44 0.18 94.11 Table 2 Flotation conditions of tin mine south selection plant Required pulp pH Flotation agent formula ∕(g·t -1 ) Ding Huang Yao N,N-diethyldithiocarbamate (abbreviation: ethyl sulphide) Shale oil Lead nitrate Pine oil Coal oil Natural pH 100 70 288 147 119 65 The beneficiation of tin, lead, antimony and zinc polymetallic ore in Guangxi Dachang uses heavy medium-re-election-flotation-re-election process. Guangxi Dachang Polymetallic Tin Mine is a very complex cassiterite-sulphide ore, of which more than 10 kinds of minerals have industrial significance. The selected process flow is to first select 40% to 60% of the waste rock in the hydrocyclone in the hydrocyclone, and the heavy product enters the pre-stage re-election to obtain the mixed concentrate (cassiterite and sulfide), and then Flotation of sulfur, the product in the tank enters the rear section and re-elected, and the tin concentrate is obtained; the middle ore and the slime in the previous section are fully floated and desulfurized, and the shale tin concentrate is re-selected; the fully flotation sulfide ore enters no Cyanide flotation separation system, producing lead-bismuth mixed concentrate, zinc concentrate and arsenic concentrate. Lead-antimony mixed concentrate, preferably divided jamesonite (only metallurgically treated), arsenic pyrite (heavy medium processing plant as weighting agent). The conditions and production indicators of the cyanide-free flotation process of the mine are listed in Table 3.
