Reverse-phase extraction and separation of minerals in ...
2021-2-8 The emission of SO2 during cement production will lead to environmental pollution, but cement clinker has a certain effect on sulfur fixation. To study the mechanism of sulfur fixation of cement clinker, we have separated the sulfur-containing minerals in cement clinkers by the three-step method of reverse-phase extraction, separation and enrichment. In addition, we have analyzed the mineral ...

Offline Solid-Phase Extraction and Separation of Mineral ...
A method was developed for the determination of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in edible oils, achieving similar limits of quantification than those obtained by online extraction methodologies, i.e., 0.5 mg/kg. The isolation of MOSH and MOAH was performed in a silver nitrated silica gel stationary phase prior to their analysis by gas ...

2013-7-7 Extraction and separation of nickel and cobalt from saprolite laterite ore were studied by using a method of microwave-assisted hydrothermal leaching and chemical deposition. The effects of leaching temperature and time on the extraction efficiencies of Ni2+ and Co2+ were investigated in detail under microwave conditions. It is shown that the extraction efficiencies of Ni2+ and Co2+ from the ...

What is separation efficiency in mineral processing?
Resolution and Separation Factor, Retention Factor, Number of Theoretical Plates. In addition to resolution, the separation factor (α) is also used as an indicator of the separation of two peaks. The separation factor is defined as the ratio of the retention factors (k), as shown in equation (3). What is separation factor in an extraction process?
