Ultrasonic-table-floatation combined desliming process

Abstract

The invention discloses an ultrasonic-table-floatation combined desliming process which comprises the following steps: at first, part of ore slime is removed from a raw ore material through an ultrasonic desliming machine; the overflow from the ultrasonic desliming machine is directly subject to tailings discarding; settled sand from the ultrasonic desliming machine is subject to separation desliming by adoption of a table; table concentrate is taken as a qualified deslimed material; table tailings are directly discarded; a foaming agent is added into table middlings, and then the mixture is uniformly stirred by adoption of a stirring tank; after the uniform stirring, floatation desliming is performed; floatation foam is taken as fine slime and directly subject to tailings discarding; andthe floatation underflow is taken as a deslimed material. The ultrasonic desliming machine utilized in the ultrasonic-table-floatation combined desliming process comprises an ore feeding pipe, an orefeeding nozzle, flow regulating plates, an ultrasonic probe, a machine shell body, an overflow dam, an overflow port, a lead wire, an ultrasonic control cabinet, water supplementing pipes, a high-pressure water pipe, a sand settling port switch, a sand settling port, a flow regulating plate bracket and an ore feeding pipe bracket. The ultrasonic-table-floatation combined desliming process disclosed by the invention has the advantages that the desliming effect is thorough and the desliming efficiency is high; the agent consumption by the ore slime during the follow-up operation can be reduced;and the application prospect is relatively broad.

Description

technical field [0001] The invention relates to an ultrasonic-shaking table-flotation combined desliming process, which belongs to the technical field of mineral processing. Background technique [0002] The source of ore slime is usually divided into two types, one is primary ore slime, ore slime formed during the ore-forming process, and the other is secondary ore sludge caused by pollution or over-grinding and crushing in the subsequent mining and sorting process. Raw slime. The so-called fine mud is usually a material with a particle size of less than 10 μm. Due to the small particle size, these fine-grained materials have a large surface area. During the mineral separation process, a large amount of chemicals will be consumed, and they will also adhere to the surface of coarse-grained minerals. Serious Affects subsequent sorting operations. Therefore, desliming treatment is often required when sorting and separating minerals, which provides a prerequisite for better s...

Problems solved by technology

[0003] For ores with high mud content, desliming is often carried out before sorting, such as zinc oxide ore with high mud content, if the mud content is too high, the foam viscosity will increase when the sulfide-amine flotation method is used It will be difficult to eliminate, and serious trough running will make the flotation index worse

Nowadays, more equipment is used for desliming, such as hydrocyclones, desliming buckets, inclined plate thickeners, etc. However, these equipments are often used alone, which cannot achieve a good desliming effect. Improvement of equipment or process, developing an efficient desliming equipment and process will be an effective method
