Abstract - Teniente smelting technology produce high copper concentration slag, which are treated to reduce the quantity of copper in the slag. The slag concentration in this slag is higher than some copper mineral weight percent. At the same time, seawater is an alternative for froth flotation, given the current prevailing water crisis. The present paper study of froth flotation of …

Managing the impact of grinding on flotation performance is the third crucial factor in plant design. Even if you can accept the low power efficiency of a mill with steel balls, you may not be able to deal with its impact of surface chemistry. Consuming so much power in a steel environment means high retention time and lots of steel contamination.

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.

71· The impact of grinding environment on flotation has been investigated for different ores. In the flotation of platinum-group minerals (PGMs) from the Overysel ore (Bushveld complex in South Africa), dry grinding produced more fine particles, led to a higher degree of liberation for the PGMs but lower recoveries than wet grinding [11].
