Abstract. Talc is a naturally occurring magnesium silicate mineral, widely used as a polymer filler. Its main differentiating features in this context are its softness (it is the softest mineral known) and lamellarity (platiness). Useful deposits are widespread and processed by conventional mining operations to produce filler grade material.

Since the surface of talc is hydrophobic and the surrounding minerals are hydrophilic, talc can be refined by flotation extraction. Talc is first crushed and powdered to segregate it from its companion minerals; then, it is sent to a ball mill for wet grinding. Particles smaller than 0.074 mm are delivered to a flotation separator.
Our core strength is concentrated in extraction and supply of premium quality talc and marble to various segment and industries globally. In addition by support of our great associates & partners we manage to perform significantly in delivery of quality type nonmetallic minerals. We believe the key factor in success of this is "performance ...
