1. with excellent chilling characteristics, this characteristic does not reduce the thermal cracking, but can affect the temperature gradient, promote directional solidification without the use of cold iron. 2. Chromite is inert and does not react with other metal oxides. It is not wetted by manganese steel water. Chromite can be successfully used in manganese steel castings. 3. Linear expansion is small, and linear expansion is a factor that may cause sand inclusion in castings, so it may be used to mix wet sand mold for large castings.

Chromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr2O4. It is an oxide mineral belonging to the spinel group. The element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite(MgCr2O4). Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and Travancore in India. Chromite is iron-black in color with a metallic luster, a dark brown streak and hardness on the Mohs scale of 5.5.

Ferro chrome (FeCr) is an ferro alloy of chromium and iron, containing 50% to 70% chromium. The ferro chrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. It can divide into Charge FeCr, Carbon FeCr, Low carbon FeCr and Micro carbon FeCr
Chromite is a mineral composed of iron, chromium, and oxygen (FeCr2O4). It is a dark-colored mineral that is commonly found in ultramafic rocks, and it is the main source of the metal chromium. Chromite is highly valued for its high chromium content, as chromium is a critical component in the production of stainless steel and other alloys. It is also used in the production of refractory materials and pigments. Chromite is notable for its high melting point and resistance to corrosion, making it a valuable mineral for a variety of industrial applications. After extracting chromium from mines located in Pakistan and Afghanistan, our dedicated processing team meticulously assesses and grades the chromium ore lumps before delivering them to our esteemed customers. Our product range encompasses multiple grades, including: 1. Metallurgical Grade: With chromium oxide content ranging from 26% to 42% (Cr2O3), our metallurgical grade chromium ore is ideal for industries requiring high-quality raw materials for stainless steel production and alloy manufacturing. 2. Refractory Grade: Our refractory grade chromium ore boasts chromium oxide content between 48% and 54% (Cr2O3) while maintaining silica content at a maximum of 3.5%. This grade is well-suited for applications where high-temperature resistance is critical, such as refractory materials for furnaces and kilns. We take pride in successfully supplying these grades to various markets, including China and Europe, catering to the diverse needs of our clients. With a substantial monthly production capacity of 15,000 tons, Bare Syndicate stands as a dependable source for fulfilling industrial demands. In addition to our expertise in chromium extraction and processing, our extensive experience in logistics and international trade allows us to provide our customers with a comprehensive solution for their supply management needs.
We Supply Quality Tested by the accredited laboratory of China and CCIC accepted, and currently used by China and other Country, passing the required Assay Test and its Elements

Chrome ore is one of the most usefull mineral due to its usage in production of metallic chromium, used as an alloying ingredient in stainless and tool steels. Chromite is also used as refectory material due to its high heat stability. Pakistan is rich with overwhelming deposits of high quality chromium ore. Pakistans chromium quality is considered to be amongst the best in the world due to ore size and its Cr:Fe ration.
