The Aim And Workflow Of The Gravity Separation

The minerals are the earth's crust due to natural physical chemical or biological effect

, the natural elements and compounds. The Earth's crust is rocky, while the rock is a collection of minerals. When the composition of a rock or some of the Content to the current level of production technology can be economically mining, processing, use of the rock it is called ore. In addition to containing useful ingredients (minerals) available in the current economic ore also contains still cannot use the ingredients (minerals), those who cannot use ingredients (minerals) are called gangue (minerals).

The purpose of the dressing is to be enriched, separated from the ore will be useful minerals (or useful component) constitute components of a single man-made high-grade ore (or compounds), the so-called concentrate. Beneficiation process is taking advantage of differences in the nature of certain aspects of the mineral ore. Gravity separation is based on the density difference between the mineral particles, and thus suffered in a moving medium gravity, fluid power and other mechanical forces, in order to achieve the process of dressing swarm of density points, referred to as the re-election. Metal ore beneficiation process, the purpose of recycled metal mineral density is higher than the gangue, then after sorting the heavy product concentrates light product tailings.

In the process of re-election, the mineral separation process is completed in motor process. In other words, it is necessary to make mineral particles with different nature to have different movement among the device of re-election - the direction of movement, speed, acceleration and trajectory, so as to achieve the purpose of mineral separation. At the same time, all the re-election process in some media. Different particle size and density of mineral particles composed of material movement in mobile media, due to their nature of differences and media flows in different ways, the mineral particles of the media on resistance, and its state of motion is different. Mineral particles group in a stationary medium is not easy to loose mineral particles of different density, particle size, shape, difficult to transfer to each other, even after stratification, it will be difficult to achieve separation.
