First, the full oil flotation method According to the different lipophilicity and hydrophilicity of various minerals, a large amount of oil is mixed with the slurry, and then the oleophilic mineral adhered to the oil layer is scraped off, and the hydrophilic mineral remains in the slurry to achieve separation. The purpose of the mineral. Second, surface flotation method The industrial application appeared in 1892, carefully grinding the dry powder on the surface of the flowing water, the hydrophobic mineral is not easily wetted by the water, relying on the surface tension surface to float on the surface, and accumulating into a thin layer to become a concentrate; Hydrophilic gangue wetted by water flows into the water as waste tailings. Third, the froth flotation method At the beginning of the 20th century, the original froth flotation method appeared, which pushed the flotation method forward and appeared many forms of froth flotation. 1. Gas flotation method 2, electrolytic flotation 3. The emergence of flotation reagents by mechanical aeration and agitation flotation method has greatly promoted the development of flotation technology, and their development is interrelated. A special heatsink is a device that is designed to dissipate heat from electronic components or devices. It is typically made of a thermally conductive material, such as aluminum or copper, and is designed to increase the surface area of the component it is attached to, which in turn increases the rate of heat dissipation.Special heatsinks are used in a wide range of electronic applications, including computers, mobile devices, LED lighting, and power electronics. They are particularly important in high-performance applications where heat can cause damage to sensitive components or reduce their performance.There are many different types of special heatsinks available, including passive heatsinks, active heatsinks, and liquid-cooled heatsinks. Passive heatsinks rely on natural convection to dissipate heat, while active heatsinks use fans or other mechanisms to increase airflow and improve heat dissipation. Liquid-cooled heatsinks use a liquid coolant to transfer heat away from the component, which can be particularly effective in high-power applications.Overall, special heatsinks are an essential component in many electronic systems, helping to ensure reliable performance and prevent damage from heat buildup.

Flotation emerged as an industrial-scale beneficiation method, which was around the end of the 19th century abroad. Its development mainly goes through the following stages.
