Zircon sand is generally found in land of ancient coastlines,some of which can be found very far inland,where the heavier mineral sands formed hardened deposits.These deposits are typically mined via dry or wet(dredge)mining techniques. Typical chemical analysis: ZrO2+HfO2:65.5-66.5% Fe2O3:0.04-0.07% TIO2:0.15-0.19% Al2O3:0.40-0.90% P2O5:0.06-0.09% SiO2(Total):32.2-33.2% Free SiO2:0.25-0.45% Physical Properties Refractive Index:1.93-2.01 Specific Gravity:4.6-4.71g/cm3 Mohs Hardness:7.5+ Melting Point:2340-2550 Packing:30/40kgs pvc bags+1mt big bag Main Applications Foundry Ceramic Chemical Glass Refractory abrasive washing Cleaning Blasting and nuclear industry etc Available Sizes:60-100mesh 80-120mesh 100-200mesh 200-325mesh 200mesh 325mesh 2000mesh

Rotary Kiln Bauxite And Shaft Kiln Bauxite Calcined Bauxite
Ashapura is a leading global supplier of Bauxite and Aluminous Laterite. Bauxite is the principal ore which is used in making Aluminium metal. The Group is a preferred to supplier Bauxite to some of the largest Aluminium producers in China, CIS countries and the Middle East. Ashapura’s Gibbistic bauxites can be processed at relatively lower temperatures (145 -C to 155 -C) thorough autoclave digestion. They can be used also for sweetening stage and for non-autoclave digestion in agitators (105 ºC). Ashapura’s decades of experience in the chemical, mineralogical and metallurgical evaluation of the Bauxite, coupled with its logistical prowess to handle more than 10 million tons of Bauxite exports annually, make it a formidable constituent of the global Bauxite supply chain. Ashpura’s copious and versatile reserves are suitable for nearly all of the applications. The Group has significant interest in up the Bauxite value chain especially in the refractory Access to the best technologies to produce value added Bauxite products like Calcined Bauxite, white fuse Alumina, Brown Fuse Alumina and Alumina.
Calcined Bauxite is obtained by calcining (heating in a Kiln) superior grade Bauxite at high temperatures (8500C to 16000C), this process removes the crystalline moisture leading to a higher alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 84 % to 88 %. Calcined Bauxite is used as raw material for manufacturing fused alumina and high alumina refractories. Ashapura produces Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc.; we are committed to provide consistency in quality and availability of product at extremely competitive prices.
Activated Bauxite is an excellent adsorbent material with multiple applications. Thermal activated bauxite is used for refining of lubricant oil and waxes. Ashapura’s activated bauxite is produced in controlled conditions to achieve maximum adsorption capacity. Activated bauxite is used in petrochemical industries to clarify and regenerate oils as aviation kerosene and paraffin. Our Activated bauxite is used as catalyst for desulfurization, deflourination, cracking, dehydrogenation, and dehydration reactions. It is used as desiccant in many chemical processes, i. e, to remove water in liquid or vapor from gases, vapors and liquids. Desiccant grade bauxite is placed towers or columns and moisture containing gas or liquid is passed through to get rid of water content. Transformer oil regeneration and reduction in color is an important application, where activated bauxite is used. It’s also finds use in the treatment of waste lubricant oils, motor oil, mineral oil and chemicals because of high adsorption capacity. Majorly these applications utilize percolation method. As a catalyst activated bauxite is used to enhance petrochemical reactions in petrochemical industry. The product is available in granular and powder form with various sizes and shapes. The uniform size distribution of Ashapura’s activated bauxite provides added advantage in afore said applications.
We are the local producer and exporter of refractory grade bauxite (Shaft kiln/Rotary kiln/Round kiln). Our bauxite is from Shanxi Xiaoyi mines. High alumina and low iron. AL2O3 85~90%min, FE2O3 1.5%max; size: 0-1mm;1-3mm;3-5mm;5-8mm;200mesh;325mesh or as buyer's option. 1mt in jumbo bag.
Bauxite, mixture of hydrated aluminum oxides usually contains oxides of Iron and Silicon in varying quantities. A non crystalline substance formerly thought to be a mineral; Bauxite is claylike and earthy and ranges in color from white to deep brown or red according to the nature and quantity, it can be calcined in shaft kiln, rotary kiln and round kiln with different specification.
