1. The automatic dosing machine manufacturer describes the preliminary preparation work - ore crushing and screening, grinding and grading (a few require washing and desliming).
This work includes crushing and screening, grinding and classification. The purpose is usually to separate useful minerals from gangue minerals, and useful minerals from useful minerals, so as to achieve individual separation and lay the foundation for screening work. Sometimes this preparatory work is Divide the materials into appropriate particle sizes to lay the foundation for screening.
2. Selection work - such as re-selection, flotation and magnetic separation, etc.
This is also the key work (or the main work) of the mineral processing process. Based on the different characteristics of minerals, different mineral processing methods are selected, such as flotation, gravity separation or magnetic separation.
3. Flotation link of automatic dosing machine
Mainly includes the following work:
1. The ore is finely ground to dissociate useful minerals. This operation is generally accomplished by a grinding machine combined with a separator.
2. Adjust the concentration of the slurry to suit the flotation requirements. In most cases, the concentration of the graded overflow before flotation meets the flotation requirements, so this work can be omitted.
3. Flotation slurry dosing treatment. This work is generally carried out in a stirring tank.
4. The initial flotation work after the slurry has been treated with chemicals is usually called roughing.
4. Product processing work - concentrate dehydration, tailings storage, etc.
It mainly includes concentrate dehydration and tailings treatment. Automatic dosing machine concentrate dehydration generally consists of three periods: concentration, filtration, and drying (sometimes required). Tailings treatment usually includes tailings storage and tailings water treatment.
