Course work topic: «Flash smelting of sulfide copper concentrates on matte with heated air blast»

Сonclusion

As a result of the calculations carried out on the material balance, the possibility of carrying out melting in a suspended state in an autogenous mode was confirmed. The output of the main products was: matte - 31.62%, slag - 32.72%. At the same time, the matte is very rich in copper - the copper content in the matte is 50%.

The heat balance calculations confirmed that the selected high degree of desulfurization (65%) also made it possible to carry out melting in autogenous mode.
In addition, the use of an oxygen-enriched blast ensured the production of gases with a high content (81.47%). And this plays an important role from an economic point of view, that is, it reduces the cost of further processing into elemental sulfur and sulfuric acid.
