The issue of producing acid from pyrite
Thread Content
We produce acid from pyrite, and recently we have experienced severe losses in the production of iron concentrate; we have yet to identify the cause. Has anyone encountered a similar problem? What could be the reason?
Is it the low yield of iron ore concentrate? Or some other problem? Be more specific in your expression.
It is calculated by taking into account the amount of ferrous iron mixed in the combustion process, as well as the output and inventory levels of iron ore concentrate; as a result, the discrepancy in the amount of iron ore concentrate is quite large
Tetrahydrate and monohydrate, basically in a 1:1 ratio
