20101110· A similar trend of decreasing recovery was also observed with regrinding in the tumbling mill (i.e., Magotteaux Mill ®). Changes in mineral flotation behaviour were investigated with respect to (i) particle size, (ii) increase in surface area, and (iii) surface contamination with size reduction in the two different mills.

2025517· Why Flotation is Superior for Slag While gravity and magnetic methods are effective for coarse particles and ferromagnetic materials, flotation shines in recovering ultrafine, oxidized, and chemically altered particles, which are common in slag. In many cases, flotation can extract metal values that represent 1–3% of slag mass—yet up to 60–80% of its economic value.
