摘要
Experiments on technical conditions of thermomagnetic methods include such contents as roasting granularity, temperature, time and thermomagnetic component separation. Based on conducting technical design and experiments on various technical aspects,the authors established a set of reasonable technical processes for sample roasting and thermomagnetic component separation. Some problems encountered in the experiments were also analyzed, which provides the basic technical support for the introduction and promotion of thermomagnetic geochemical methods.
