In this study, the metallurgical performance of typical copper sulfide minerals, molybdenite as well as gangue minerals (, pyrite, tennantite, and enargite) under different pH and Eh conditions of the flotation cell were investigated. The copper and molybdenum processing plant at the Sungun complexIran were selected as a case study.
When and How to Use Copper Fungicide in Your Garden
Copper's a metal and, when put in a liquid state, can be sprayed or wiped on plants. The copper penetrates the leaves of the plant and can kill harmful organisms such as funguses. There are many types of copper products that you can choose from. Copper sulfate, which is sometimes referred to as bluestone, was one of the first types of copper ...
A fresh approach to sulfide ores
· A smelting workaround. The traditional route for extracting copper from sulfide ores is smelting. Yet there is a growing case for leaching sulfides from lower grade ore bodies and especially for those ore bodies containing problematic elements like arsenic, which make smelting less economical. Smelting is increasingly expensive because, in ...
