- Mineral Beneficiation Screening
In mineral processing, arsenic-bearing minerals are particularly difficult to separate from their non-arsenic counterparts because they possess similar surface properties. Peptides are well known for their target specificity and can offer a 'green' alternative to traditional flotation reagents. However, the use of peptide technologies in …
