slag бутлах flotator

A flotation recovery method of silicon from metallurgical-grade silicon-refined slag (silicate) using sodium silicate (SS) as the depressant was proposed. The solution chemistry, contact angle, and zeta potential measurements were used to understand the interaction mechanisms of SS on the silicate.

The oxygen-containing functional groups and fine particle size of residual carbon in gasification slag may affect flotation efficiency [15]. Traditional collectors, such as kerosene or diesel oil, cannot adsorb the unburned carbon surface containing oxygen functional groups. The total consumption of flotation reagents can reach 5–50 kg/t.

After copper recovery by flotation, the remaining part of the slag is considered waste and disposed of in the slag dump area. However, even after copper recovery, copper slag flotation tailings (CSFT) may still contain several metals in varying amounts. However, the complexity and low metal concentration have undermined the …

The nature of copper slag flotation is unique due to the high temperature in the flotation pulp and high metallic copper content in the feed. Despite its great potential for valorizing slag, copper slag flotation remains challenging due to the deactivation of traditional dithiocarbonate (DTC) collectors (e.g., butyl xanthate) under high temperatures.

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

Ultrasonic flotation has a more significant crushing effect on entrained-flow gasification coal fine slag particles than conventional flotation. Furthermore, ultrasonic benefits the flotation selectivity because the ultrasonic not only reduces the glass beads coating on the slag surface but also decreases the entrainment of high-ash fines.
