talc mineral effect


At low concentrations (less than 3 weight%), talc acts as a nucleating agent, reducing spherulite size and shortening processing time [7]. At higher loadings (10-40 weight%) it acts as a reinforcing filler, increasing tensile modulus and stiffness, but reducing strain-to break and impact strength [8].

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.
