together with one of the major platinum companies. The major factors of process value come down to capital and operating efficiency. Generally, the focus to drive value is largely in the mining and concentration steps in which the most losses are incurred. For example, total losses in the mining step before the process, account for 27% compared

If this is the case, after gold precipitation, go for platinum metal directly, do not precipitate the salts - management of the process would be much easier. You can conveniently use zinc metal if you aren´t going for 3N+ metal - as traces of zinc evaporate at very high temperatures required for platinum melting.

August 29, 2023. oil refinery catalysts are indispensable in oil refining and petrochemical processes. These catalysts accelerate reactions, converting crude oil into essential products. The diverse Mineral adsorbents and catalysts fall into heterogeneous and homogeneous categories, shaping reactions and molecular transformations.
