ALVARADO-BAWAB, María; VANEGAS-CHAMORRO, Marley  e  VALENCIA -OCHOA, Guillermo. Statistical analysis of a hydrocyclone system for coals benefit. Prospect. [online]. 2016, vol.14, n.2, pp.53-61. ISSN 1692-8261.  https://doi.org/10.15665/rp.v14i2.652.

The aim of this study was to evaluate the effect of particle size, coal concentration, discharge diameter and type of hydrocyclone on the mass yield, organic recovery efficiency, and the ash and sulfur removal percentages in a Colombian coal from the Valle del Cauca department. A washing system with two hydrocyclones was developed, one with a flat bottom and the other with a conical bottom. A randomized fractional factorial design (IV order resolution) was built in order to determine the significant effects on the washing process.

The hydrocyclone discharge diameter was the most influential factor on the mass yield for both hydrocyclones. The study concluded that the conical bottom hydrocyclone should be used for getting a better yield mass; the flat bottom hydrocyclone should be used to remove the highest amount of ash and sulfur content during the process.
