Pyrolysis of biomass to produce H-rich gas facilitated by simultaneously occurring magnesite decomposition

Carbon Resources Conversion
This study investigated how biomass pyrolysis varies with the different fractions of magnesite mixing into biomass. The pyrolysis occurred with simultaneous decomposition of magnesite without use of any gasification reagent, and was analyzed in terms of ...

Determination of the PZC of magnesite and talc by the ELS technique [PDF]

Acta Montanistica Slovaca, 1998
The paper presents the results of zeta potential measurements of magnesite and talc by the laser - Doppler electrophoretic light scattering ( ELS ) technique. The PZC of magnesite is located at pH 7,2 , while that of talc at pH 2,7.

Proposal of Support Planning System for Magnesite Mining Operations Based on an Assortment Volume Sale Forecasting

Management Systems in Production Engineering
In the long term, the mining industry can be regarded as market volatile in terms of commodity price movements and sales. Although the general demand for raw materials is increasing, volatility in the different segments of the industry is visible.
