A process for producing fuel by cracking a plasticsderived liquid, which is obtained from a pyrolysis process, using a dolomite alyst. The plasticsderived liquid is produced by the pyrolysis of plastic waste, such as of one or more of polyethylene, polystyrene or polypropylene. The plasticderived liquid is first subjected to a semibatch alytic cracking reaction over a very low cost ...

The phosphate ore flotation is achieved through the surface electrical behavior difference among apatite, dolomite and quartz, but it is usually affected by the dissolved ions from pulp, especially Ca2+ and Mg2+. The zeta potentials of apatite, dolomite, quartz, and phosphate ore in different solutions were measured to discuss the surface electrical behaviors of them in this study.

Magnesium oxide suitable for the use in basic refractories was prepared from dolomite (CaMg(CO3)2) by hydrochloric acid leaching, precipitation with CO2 and thermal hydrolysis. Leaching of the dolomite ore in aqueous hydrochloric acid solution was investigated with respect to the effects of time on dissolution of the dolomite sample. The dependence of the observed dissolution rate on pH was ...
