Oct 1, 20201. Introduction. Greenhouse gas emissions are a global issue and the leading cause of the global climate change. One tonne of Portland cement manufactured produces approximately one tonne of carbon dioxide (Hasanbeigi et al., 2010).Therefore, developing materials with lower CO 2 emission as alternative to the traditional Portland cement is important. . Alkali-activated materials (AAM) are ...

Precipitates are formed with hydroxide, fluoride, carbonate, oxalate, and phosphate anions. The actinide M4+ ions form insoluble fluorides, iodates, arsenates, and oxalates; the nitrates, sulfates, perchlorates, and sulfides are all water soluble. The MO+ 2 ions can be precipitated from concentrated carbonate solutions as potassium salts.

In a mineral processing plant or "mill", size reduction takes place as a sequence of crushing and grinding processes. Crushing reduces the size of run-of-mine ore to such a level that grinding can be carried out (usually between 12 to 19 mm top size). Grinding continues until mineral and gangue are substantially in the form of discrete particles.
