Answer:
A hydraulic press is a machine press using a hydraulic cylinder to generate a compressive force.[1] It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England.[2] He invented and was issued a patent on this press in 1795. As Bramah (who is also known for his development of the flush toilet) installed toilets, he studied the existing literature on the motion of fluids and put this knowledge into the development of the press.[3]
Answer:
Hydraulic washing is used for the ores that have tin or lead in them. This is because tin and lead are heavier than the gangue particles.
Explanation:
The hydraulic separation method of concentration of ore is based on the difference in the specific gravities of the metallic ore and gangue particles. Generally, metal ores are heavier than the gangue particles. The hydraulic separation method uses this property for the concentration of the ore. Due to this reason, it is considered a type of gravity separation.
Cassiterite and haematite are concentrated with the help of the hydraulic separation method.
> Cassiterite is the main ore of tin. It is a reddish, brownish, or yellowish mineral that consists of tin dioxide. It has the chemical formula as SnO2SnO2. It is generally opaque, but it is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem.
> Haematite is a common iron oxide ore. It has the chemical formula Fe2O3Fe2O3. It has a steel black color or we can say a silver-grey colour. It can also be brown to reddish-brown or red. It forms the shape of crystals.
> During the hydraulic separation process, the powdered ore is washed by an upstream stream of running water. The lighter gangue particles are washed with the water leaving behind the heavier ore particles.
The ore is crushed to a fine powder and concentrated by gravity separation by washing with a current of water when most of the lighter gangue particles are removed.
