What is a geopolymer? Introduction – Geopolymer Institute

Apr 05, 2006 updated: August 17, 2012. Geopolymers are chains or networks of mineral molecules linked with co-valent bonds. They have following basic characteristics:

Tailings Mineral Industry Solution

Again the addition of polymer aids in the separation and thickening process. The disc filter uses vacuum to dewater the magnetite iron ore concentrate and discharges a relatively dry cake which is sent for pelletizing. This process allows ore of very low magnetite content to be processed into a high quality product. Tailings
