75 80 85 86 87 88 90% Ai2O3 Calcined bauxite in refractory Product Description  Calcined Bauxite is produced by sintering high-alumina bauxite in rotary, round or shaft kilns at high temperatures of 1600℃-1800℃. This process of calcining (heating) bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness, low iron, and

What’s kind of bauxite used for Road paving?  High Friction Surfacing bauxite is also called buff bauxite or Chinese Buff bauxite, normal size is 1-3mm. Chinese buff calcined bauxite mainly used for the majority of public sector systems will specify that Calcined Bauxite be used in their road.  Buff Bauxite is a natural, very hard

Shaft kiln bauxite, the bauxite calcined by shaft kiln. The raw material – bauxite ore is loaded from the top of the kiln and coal powder and combustion improver; the fire of calcination comes from the kiln bottom, about 1300-1400 degrees. After the complete calcination, the bauxite is carried out from the bottom. Comparing with

Aluminum industry. Use for the national defense, aerospace, automotive, electrical, chemical engineering, daily necessities, and so on. Precision casting. Bauxite clinker is processed into a fine powder, then made into casting molds. Use for military, aerospace, communications, instrumentation, mechanical and medical apparatus. Refractory products. Bauxite clinker refractoriness up to 1780 ℃. It has stable chemical

Bauxite is usually strip mined because it is almost always found near the terrain’s surface, with little or no overburden. Approximately 70% to 80% of the world’s dry bauxite production is processed first into alumina and then into aluminum by electrolysis as of 2015. Bauxite rocks are typically classified according to their intended commercial application:
