A low-grade siliceous sedimentary phosphate rock assaying 22.05% P205 was upgraded by double float (direct and reverse) technology. The rock contains collophane (carbonate fluorapatite) as the valuable phosphate mineral along with siliceous, carbonaceous and clay minerals. A process was developed which yielded a high-grade phosphate …
Jaw crushers are used to crush and reduce the size of various materials, including rock and ore. They work by using compressive force to break down the materials.
Either of the two types can be built to handle the hardest and toughest rock or ore that can be economically mined or quarried. The jaw crusher, because of its box-frame construction, and simple toggle mechanism, is especially well adapted to extra heavy design for the crushing of extremely tough materials: in this respect it holds some …

Horizontal shaft impact crushers can be primary or secondary. They are better suited for softer, less abrasive stone in the primary stage and more abrasive and harder stone in the secondary stage. Selection of Rock Crushing Equipment. Choosing the right rock crusher is based on different factors and these include: Ore characteristics.
Roll crushers consist of two or more adjacent rolls placed parallel to each other and rotated in opposite directions. Single roll crushers are also available which rotate a single roll against a fixed breaker plate. Mineral or rock particles placed between the rolls are nipped and then crushed as they pass between the rolls. Rolls are held against each …
