Problems solved by technology

[0004] Suspended vibrating conical concentrator is a new type of fine-grained ore dressing and re-separation equipment developed in recent years (see the patent of Kunming University of Science and Technology for details). Vibration, it has the characteristics of large processing capacity, low energy consumption, simple operation, easy management, etc., but the enrichment multiple of this type of concentrator is not high, for the beneficiation of minerals such as low-grade ore or tailings that require a higher enrichment ratio Not ideal, the grade of the concentrate is not high, and it cannot meet the product quality requirements very well

Embodiment 1

[0016] Embodiment 1: Mineral materials are derived from tin tailings in a certain place, the selected grade of Sn is 0.18wt%, and the technological process is adopted image 3 The method shown is carried out. Firstly, a suspension vibrating conical concentrator is used for roughing. The operating parameters are: the gyratory vibration frequency is 363 rpm, the disk surface movement period is 220 seconds / rotation, and the ore concentration is 23wt%. The tin rough concentrate obtained by the suspension vibrating cone concentrator is then separated by the vibrating cone concentrator using a shaking table to select the tin coarse concentrate to obtain the tin concentrate. The operating technical parameters of the slime shaker are: the stroke is 12mm, and the stroke frequency is 230 times / min.

Embodiment 2

[0018] Example 2: The ore material is derived from lead-zinc tailings in a certain place, and the process mineralogy properties of the sample are investigated Pb: 0.58%, Zn: 1.82%, using the process flow image 3 The method shown is carried out. Firstly, roughing is carried out with a suspension vibrating conical concentrator. The operating parameters are: the gyratory vibration frequency is 352 rpm, the disc rotation period is 230 seconds / rotation, and the ore concentration is 25%. The lead-zinc rough concentrate obtained by the suspension vibrating cone concentrator is then separated by the vibrating cone concentrator with a shaker to obtain lead-zinc concentrate and lead-zinc medium ore. The operating technical parameters of the slime shaker are a stroke of 12mm and a stroke rate of 230 strokes / min.

Abstract

The invention relates to a process of reselecting fine-grained tailings by combining a suspension vibration conical surface concentrating machine and a table concentrator. The invention relates to a concentrating method which aims at fine-grained low-grade heavy minerals or tailings with difference of specific gravity. The process comprises the following steps that more than 80% of tailings or low-grade ores are crushed to be less than or equal to 0.15 mm, firstly, the suspension vibration conical surface concentrating machine is adopted to reselect with the concentration ratio of 3.5 to 8.5, and then selected ore particles are reselected by the table concentrator with the concentration ratio of 3.2 to 28. The process has the advantages of large treatment capacity, high concentration ratio, low energy consumption, high separation efficiency and no pollution to the environment, a concentrating reagent is not used, and a new way is provided for redeveloping new and old tailings discharged by concentrating mills of tin, tungsten, iron, lead, zinc and the like or utilizing low-grade ores.

Description

technical field [0001] The invention relates to a beneficiation method for fine-grained low-grade heavy minerals or tailings with different specific gravity, especially a beneficiation method for sorting fine-grained tin, iron, tungsten, lead, zinc, titanium, manganese and other heavy minerals method. Background technique [0002] With the deepening of resource mining and utilization, modern mines have to develop increasingly poor, fine, miscellaneous ores and hundreds of millions of tons of tailings accumulated over a long period of time. Especially in some old mines, the tailings produced due to the mineral processing technology have great secondary utilization value. At present, the beneficiation equipment for processing such fine-grained heavy minerals has unsatisfactory recovery effect due to its low processing capacity, large floor area, and high energy consumption, and it is difficult to generate economic benefits. In order to obtain economical and effective develop...
