Problems solved by technology
Since powder minerals cannot directly measure the wetting contact angle, the measurement results after the powder is pressed into tablets often have large errors and poor reproducibility
As a result, it is difficult to characterize the floatability of powdered minerals, and there is also a method to characterize the floatability of powdered minerals in disguise, but the results are not accurate enough
In order to evaluate the floatability of powdered minerals, simulated flotation tests are generally used, but the results are also easily affected by differences in environmental factors and process differences

A powder mineral floatability analyzer relates to the mineral flotation technology field. The powder mineral floatability analyzer comprises a pedestal component, a rear seat component, a bubble generating component, an electromagnetic execution component, an initial position adjustment component, and a monitoring device. The rear seat component and the monitoring device are connected to the pedestal component. The bubble generating component, the electromagnetic execution component and the initial position adjustment component are successively arranged from top to bottom and are connected tothe rear seat component. The bubble generating component comprises a first screw micrometer, a micro syringe, a flexible tube and a capillary glass tube which are successively connected. The electromagnetic execution component comprises a vibration source which sleeves an outer side of the capillary glass tube, a driving module and a glass container. One end of the capillary glass tube is immersedin a liquid of the glass container. By using the powder mineral floatability analyzer, bubbles are controlled to extrude minerals and adsorb powder mineral particles under a specific condition. Floatability of minerals is qualitatively analyzed through comparing energization time and an extrusion degree in the specific condition so that a problem that the floatability of powder minerals is difficult to determine is solved.
Description
technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a powder mineral floatability analyzer. Background technique [0002] The floatability of minerals reflects the difficulty of mineral flotation, mainly depends on the natural surface physical and chemical properties of minerals, usually measured by the size of wetting contact angle, measured by contact angle meter, the larger the wetting contact angle, The buoyancy of the tested mineral is stronger. Taking the wetting contact angle of water on the surface of a solid mineral as an example, the angle between the tangent line of the gas-liquid interface and the tangent line of the solid-liquid interface at the intersection point of the three-phase interface of the liquid droplet on the horizontal surface of the solid mineral is the wetting contact angle. Because powder minerals cannot directly measure the wetting contact angle, the measurement results after the powder is ...
