The slag was crushed in a jaw crusher and ground in a ball mill and then sieved. N-ethyl-O-isopropyl thiocarbamate (Z-200), ethyl xanthate, butyl xanthate, isopentyl xanthate and butylamine dithiophosphate were used as collectors; terpineol oil as frother; sulphuric acid, lime, sodium hydroxide and sodium carbonate as pH regulator.

Introduction. Steel slag is the main solid waste generated in the steel-making process, accounting for 15 to 20% of crude steel output [1]. China's crude steel output in 2021 was 1.035 billion tons [2], more than half of the global crude steel output (1.9505 billion tons) [3], and the steel slag output exceeded 120 million tons.

Sulfidation treatment of copper smelting slag. In the sulfidation experiment, the particle size of the synthesized slag was controlled below 80 mesh (178 µm).The mixture of CaSO 4 and anthracite was pelletized at a pressure of 1.0 MPa in a Ø 4 mm pressing tool, and the weight of every pellet was roughly controlled to be 0.04 g. Then …

The moisture in steel slag when it enters the mill is 6.9%, and the Bond work index of the steel slag is 28.6 k Wh/t. The yield of the mill ground steel slag that is not treated via magnetic separation is 19.98% lower than that which is treated via magnetic separation. From this, it can be seen that the iron content in steel slag is ...
