how to bulid leaching copper

A flowsheet of a conceptual copper leaching process can be constructed where chalcopyrite (or other copper sulfide and oxide minerals) can be leached in alkaline glycine systems, followed by solidliquid separation and recovery of the copper from solution with restoration of the glycine to an alkaline pH in the range 9 < pH <

Modeling of Copper Leaching. In order to build the leaching model, two assumptions have been made as follows: (1) the concentration of copper ions in the wood is distributed uniformly; (2) the cumulative water spray time was equivalent to continuous soaking.

Your body uses copper to carry out many important functions, including making energy, connective tissues, and blood vessels. Copper also helps maintain the nervous and immune systems, and activates genes. Your body also needs copper for brain development. How much copper do I need?
