Acid Wash Process For Milling

Solved in acid solution can re-adsorb.11 water washes after milling remove re-adsorbed species, often in amounts comparable to those initially removed by milling.Also while rha contains significant phosphorous as phosphates,12 its high solubility in dilute acid reduces its presence below detectable levels early in the process.

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
