A separation apparatus [2] for separating minerals or other particulate matter, including a housing [3], a particulate inlet [4], a fluid inlet [5] and an outlet [6]. The separation apparatus [2] separates the minerals or other particulate matter, based on density. This is achieved by ingressing a fluid into the fluid inlet [5] to create appropriate fluidization of the particulate matter within the housing [3]. Low density material may typically be extracted from an upper end of the housing [3], whilst higher density material may be typically extracted from a lower end of the housing [3]. The invention is particularly useful for separating minerals such as coal from impurities such as silica and pyrites. |
