Screening in Mineral Processing and The Importance of High ...

2020-4-8  Both the mining and mineral processing industry hugely utilise the screening process since it can effectively separate and filter out important minerals from the newly extracted materials. Once the minerals are filtered and separated from excess materials, they will be processed further depending on their commercial use.

Step 1: Screening – EIA Online Learning Platform

Screening is the first stage of the EIA process which results in a key EIA decision, namely to either conduct the assessment (based on the likely significant impacts) or not conduct it (in the anticipated absence of such impacts). Screening needs to follow specific procedures often described in the legislation so all the projects follow the same process.
