bauxite benefication equipment
Bauxite is among the most important industrial minerals and it being the aluminium ore, may be the principal raw material for your manufacture of alumina. Bauxite can also be used being an important raw material for many other products like Alumina, Cement, Abrasives, High strength proppant, Emery, Alum etc.. Mined bauxite resembles small red pebbles, called pisolites, averaging about five millimetres in diameter.
Bauxite Mining
Bauxite exists in free-flowing form, which makes it relatively easy to seek out of the ground. Front loaders load the bauxite into 150 tonne bottom-dump trucks, which consider the ore to some dump station for transportation towards the processing plant (known as a beneficiation plant) by rail and belt conveyor.
The ROM Bauxite passes through many processes prior to it being converted into export grade rich in commercial value. After the raw Bauxite is mined, it not just undergoes mechanical procedure for crushing, sizing and screening.
Bauxite crushing & grinding plant
Bauxite is mined and crushed at bauxite deposit. Crushed bauxite ore will then be transported by overland conveyor for the refinery. Mining starts with plants and creatures surveys. Topsoil and overburden is removed and kept to be used in rehabilitation.
The bauxite is excavated and brought by truck to primary and secondary crushing stations at the mine site. The main crusher will take rocks as huge as 1.5m across. By the time the ore comes from the opposite end the biggest rocks are under 180mm. Another crushing plant further cuts down on size to lower than 30mm. The crushed ore is fed into a stockpile, able to be carried by conveyor towards the refinery.
As an expert bauxite crusher, bauxite grinding mill manufacturer in China, BinQ Machinery has manufactured primary jaw crusher, impact crusher, fineness cone crusher for bauxite ore.
Our bauxite crushing plant is widely used in bauxite beneficiation plant in Guinea, Vietnam,Jamaica,Brazil,Guyana,India,Iran, China, Australia,Greece, Suriname, Kazakhstan, Venezuela, Russia, United states of america etc.
Bauxite beneficiation processing
At the bauxite beneficiation plant, the raw bauxite ore is going to be fed into primary crusher for primary crushing.
The crusher is used to break the ore as a result of an inferior size suitable for transport across the conveyor belt to the refineries. The crushing plant comprises of numerous components which include a vibrating screen, jaw crusher, impact crusher, cone crusher, vibrating screen etc.
Fine material drops from the vibrating screen while larger material passes within the screen to the jaw crusher that breaks in the large rocks. The information that passes through the vibrating screen and jaw crusher is collected and passed with the sizer that further cuts down on size the information prior to it being passed to the conveyor belt. The last sized the crushed bauxite ore is approximately 7.5cm or less in diameter.
After the crushing process, the the bauxite is screened and washed to remove fine particles. It is then positioned on stockpiles, which can be loaded onto ships. Then your bauxite ore is going to be refined into alumina on the smeltery.
At the smeltery, bauxite ore is going to be ground into fine powder (under 0.1mm or even smaller) by grinding mill including rod mill, ball mill ,Raymond mill, questionable mill etc.
