How can I reduce the amount of arsenic-containing matte? Experts, please give me some suggestions
Thread Content
Our furnace is used to process copper slag; the arsenic content in this slag is about 7 times higher. The amount of matte and red matte produced each time is very small, while white matte (arsenic-containing matte) accounts for 60% of the total output. What can be added to reduce the amount of arsenic-containing matte? I seek advice from experts
I have been studying this problem for a long time, but I still haven’t found any effective solution. Theoretically, increasing the sulfur content in copper slag can reduce the production of arsenic-containing matte. From a phase perspective, arsenic-containing matte exists in the form of copper arsenide and metallic copper; copper arsenide is difficult to handle, but metallic copper can be converted into matte by increasing its sulfur content. In production practice, adding pyrite during ingredient preparation yields no significant effect.
