Researching the relationship between duration of drying gold-quartz ore geological samples and layer thickness of sample material
Drying geological samples is an important part of the preparation of mineral material samples for the analysis. Therefore, improving the process of drying geological samples of mineral raw materials is an urgent task. The most promising method of drying is the drying of samples in the microwave oven. The research focuses on the influence of layer thickness of sample material on the duration of drying geological samples of gold-containing ores. It is shown that the drying time depends on layer thickness of the sample, in this case, the thickness of the sample should be no more than 4,5 cm. If the sample layer thickness is more than 4,5 cm, the drying process is uneven (the top layers are overdried, the lower layers are underdried). The authors recommend to use containers with layer thickness not more than 4,5 cm when drying samples weighing 500 g and when drying samples weighing more than 500 g to divide samples into two approximately equal parts. The optimal layer thickness of sample material allows to increase the rapidity of drying and the preparation of samples for the analysis by 2-4 times.
