Cement Clinker Production - an overview ScienceDirect Topics

Used in the plant, limestone (55–60%), marl (35–40%), and copper slag (2.5–6%) are used as cement raw materials for the production of clinker. The clinker is then finely ground in a ball mill grinding circuit together with a small amount (typically 4%) of gypsum to produce cement in the Turkey Trabzon Cement Plant ( Alp, Deveci, Süngün, 2008 ).

Preparation of Portland Cement with Gold Ore Tailings - Hindawi

The disposal of gold ore tailings (GTs) has been a very difficult problem for a long time. Thus, this study explored a new approach to the management of GTs by preparing Portland cement. Physical properties, reaction mechanisms, and hydration product types of cement prepared with GTs (C-GTs) and ordinary Portland cement (C-SS) were compared. X-ray
