Physical Chemistry of Roasting and Leaching Reactions for Chromium Chemical Manufacturing and Its Impact on Environment - A Review
Chrome plants play a crucial role in the mining industry, as they are responsible for extracting and refining chromite ore, which is a valuable source of chromium. Chromium is an essential element used in various industries, including stainless steel production, chemical manufacturing, and metallurgy. Understanding the chrome …
This article reviews the major process flow sheets in practice for the recovery of chromite values from various types of ores and critical issues related to chromite ore beneficiation. Emphasis is placed on different processes developed in identifying and solving critical plant problems.
Prior to commencing chromite mining in the Ring of Fire, baseline studies should be undertaken to determine the possible natural occurrence of Cr (VI) in soils, untreated chromite ore and surface/groundwater, as well as sources thereof. During mining and ore processing, dry milling was identified as the only process step with the …

Sukinda valley in Jajpur district of Odisha contains about 98% of chromite reserve and it is exploited mostly by opencast mining process since 1950. Hexavalent chromium is a highly toxic form of chromium metal mainly used in different industrial applications for its anticorrosive properties.Due to open cast mining process lots of over burden are being …
Chromium ore is typically found in the Earth's crust in the form of chromite, which is a dark, black to brownish-black mineral. Chromite is composed of chromium, iron, and oxygen, with the chemical formula FeCr2O4. Chromium is usually extracted from chromite ore through various metallurgical processes.
Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore …
The mining process generates two types of ore—hard/lumpy and soft/friable. The mined high-grade lumpy ores are directed to ferro chrome plant after …
The chromium industry comprises the mining of chromite ore and the manufacturing of chromium chemicals and metal, ferrochromium, stainless steel, and chromite refractory products.
Spiral is widely used to concentrate beach sands, iron, gold, sulfide minerals, chromite, as well as in the coal washing industry [ 2, 4 ]. Spirals have long been used to concentrate chromite deposits due to their relatively low operating costs (compared with other processing methods) and the simplicity of the separation process.
Oxidation treatment of chromite ores is a commercially applied process for producing mechanically strong pellets for smelting operation in submerged arc furnace. The oxidation behaviour of chromite ores which essentially determines pellet quality bears a strong relationship with ore chemistry, heat treatment, temperature and time. The …
For this reason, early test work had defined an overall saleable chromite recovery limit ranging from 60–70%. The following case study focuses on the process development testwork specifically targeted at increasing chromite recovery without compromising finished product quality.
This investigation, referenced above, highlights the importance of the finer grades of chromite sand to meet the requirements of iron and steel castings. Unfortunately, this geological sourcing did not become commercial for several mining and manufacturing reasons but not because of foundry applications.
In countries where chromite is mined, it may constitute a primary source of airborne Cr ( Guertin, 2004 ). In most mining areas, the endpoint production of Cr is probably the most significant source of Cr in the air. The geological process causes Cr in the air to be associated with suspended particulate matter.
