Embodiment 1

[0047] After the fine-grained tin pulp is classified, it enters the Φ6m thickener after dehydration. The function of the Φ6m thickener is to partially precipitate and dehydrate and buffer and stabilize the ore feeding, creating conditions for uniform ore feeding in subsequent operations. The sand settling of the Φ6m thickener Enter the flotation operation for whole grain flotation. The floating tin process is carried out in two steps. In the first step, the full-grain grade of the Φ6 meter thickener with a tin content of 0.5% enters the flotation. The 0.4% tailings enter the first and second screening, and the final tailings with a tin content of less than 0.2% are produced and enter the shaker system for scanning and recovery; the concentrates of full-size roughing I and roughing II Merge and carry out full-size selection I. In the full-size flotation process, an appropriate amount of regulator sodium carbonate or sodium humate is added, with a weight concentration of 1-2%, a...

Abstract

The present invention relates to fine and superfine cassiterite recovering technology. The whole production process of recovering cassiterite includes the following steps: collecting the fine grain ore slurry, dewatering to stabilize, floating all cassiterite of different sizes by means of proper amount of floating agent, dispersion dewatering, shaking table recovering large cassiterite, dispersion floating the desilting from dispersion dewatering, and depositing and dewatering the ultimate tin concentrate.

Description

technical field [0001] The invention relates to a mineral processing technology, in particular to a novel mineral processing technology for recovering cassiterite in primary and secondary ore slimes of tin metal mines. Background technique [0002] The Dachang ore field in Guangxi is a polymetallic sulfide ore dominated by cassiterite, with many types of ore, ore composition and ore properties. Therefore, the content of cassiterite in the fine-grained and micro-fine-grained pulp produced after entering the concentrator is large, and the effective recovery and treatment of this part of the pulp has become a major problem in the mineral processing work. In the past few years, the attached The technological process shown in Fig. 1 (seeing accompanying drawing 1 of description), this process technology is briefly described as follows: [0003] All the primary and secondary slimes enter the 6-meter thickener after concentration and dehydration, and the overflow of the 6-meter th...
