Chromite was initially used as a refractory in france along with magnesite and dolomite (other refractory minerals). up until the 1890s, bricks of solid chromite cut straight from the mine were used without further refinement or processing. these are called dressed blocks of ore.
The chromite powder used in manufacturing refractory bricks and cement provides the necessary thermal resistance to avoid cracking. if the refractory materials were to crack or wear down prematurely during the repeated heating and cooling processes, they could cause a loss of heat that would drive production costs through the roof in a best ...

Chromite is a member of the spinel group and is the only economically important ore mineral of chromium. it is used extensively by the metallurgical industry as feedstock for ferroalloy production [1,2,3,4].chromite ore is commonly classified into different grades based on the cr/fe ratio as well as the cr 2 o 3 content.
Throughout mineral processing, both the state of the ore and flow rates change constantly. equipment can be subjected to a wide range of varying wear and impact effects so it is critical when selecting wear protection lining systems that each application is analysed individually.
Wear-resistant slurry pump is a suitable for conveying the slurry with concentration below 65%; moulding wear-resistant wet parts make fluid more stable and fast, and reduce the internal fluid disorders improving efficiency.
