High-efficiency pulp modifying machine for molybdenum tungsten ore flotation technology and implementation method thereof

Abstract

The invention relates to a high-efficiency pulp modifying machine, which comprises a pulp mixing box, a material silo connected to the lower part of a side surface of the pulp mixing box and a medicament barrel connected to the bottom of the pulp mixing box. The pulp mixing box comprises a box body and a rotating shaft assembly which is rotatably connected to the box body. An air compressor and amotor are arranged on the upper surface of the box body. The rotating shaft assembly comprises a rotating shaft body, a drug spray bin arranged below the rotating shaft body, and an air inlet connecting pipe and a drug inlet connecting pipe which are respectively arranged at the upper end and lower end of the rotating shaft body. A discharging pipe is arranged at the lower part of a side surface of the material silo. The discharging pipe is provided with a first feed pump. A drug outlet pipe is arranged at the lower part of a side surface of the medicament barrel. The drug outlet pipe is provided with a second feed pump. The invention also provides an implementation method of the high-efficiency pulp modifying machine for the molybdenum tungsten ore flotation technology, comprising the following steps: mineral grinding; pulp blending; pulp modification; and pulp flotation. The high-efficiency pulp modifying machine of the invention has strong reliability. By the adoption of the high-efficiency pulp modifying machine, pulp and a medicament are fully mixed, cost is saved, and flotation precision and yield of mineral are raised.

Description

technical field [0001] The invention belongs to the technical field of ore slime flotation, and in particular relates to a high-efficiency ore pulp reformer used in the flotation process of molybdenum-tungsten ore and an implementation method thereof. Background technique [0002] Molybdenum and tungsten are important strategic resources in my country and are widely used in iron and steel metallurgy, chemical industry, aerospace, electronics and other technical fields. In recent years, with the reduction of high-quality molybdenum and tungsten resources, rich ore resources are increasingly exhausted, and various poor, fine and difficult-to-select molybdenum-tungsten ores have become the source of molybdenum and tungsten resources. However, in the process of processing, due to the fine particle size of the useful minerals, to recover the minerals, the minerals must be ground and then flotation. Due to the storage conditions of molybdenum and tungsten metals, their surface hy...

Problems solved by technology

However, while these studies have achieved some results, they still have not achieved a breakthrough in efficient pulping technology, and the existing pulping equipment is difficult to fully meet the requirements of high dispersion and high-efficiency collision contact unique to the flotation of high-ash, hard-to-float slime

[0004] The impeller of the existing mixing tank is relatively high from the bottom of the mixing tank, and the bottom is prone to sedimentation. The rotational force generated by the impeller cannot take away the sediment at the bottom, so the bottom area has long-term sedimentation of slime; The concentration of the pulp and the pulp flowing out of the mixing tank changes, so the dosage is affected, which leads to confusion in the flotation process
