Flotation separation of wolframite from calcite using a new trisiloxane surfactant as collector
International Journal of Mining Science and Technology, 2023 Since wolframite is usually associated with calcite, the separation and enrichment of wolframite by froth flotation remains a great challenge. Herein, a novel trisiloxane surfactant N-(2-aminoethyl)-3-aminopropyltrisiloxane (AATS) was successful ...
