Mineral Liberation

Igor Željko Tonžetić, in Iron Ore (Second Edition), 2022. 5.3.6 Liberation, locking, and association. Historically, mineral liberation has been used as a proxy for the "processability" of a particular mineral, since the many properties of minerals that could allow for concentration and processing could not be directly measured from auto-SEM …

Mineral Drying

Mineral Drying. Drying is a critical aspect of mineral processing; throughout the journey from ore to end product, the ability to control moisture content helps to reduce shipping costs, streamline downstream processing, and produce a refined product. While mineral dryers may appear the same as other industrial dryers, they are typically built ...

Behavior of talc and mica in copper ore flotation

In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase. The copper grade and recovery were affected in the presence of only 7% talc. On the other hand, muscovite influenced the pulp phase via affecting the pulp rheology.

Behavior of talc and mica in copper ore flotation

Talc causes processing problems due to its hydrophobicity which makes this mineral naturally floatable. In addition, as talc is a magnesium silicate mineral, large quantities of talc in flotation concentrates cause problems during smelting, often resulting in the imposition of smelter penalties for mineral processing companies ( Beattie et al ...
