PYROXENITE MIINING
Pyroxenite is an ultramafic plutonic igneous rock. Ultramafic means that more than 90% of the rock is composed of magnesium- and iron-rich minerals like pyroxenes, amphiboles, and olivine.
Pyroxenite used as Dual flux for pelletisation. The tailor-made dual flux, developed through thermodynamic modelling, works well for a wide variety of iron-ore fines. The innovation resulted in a 12-percent increase in the productivity of the pellet plant.
It has been established that silicate mineral flux (Pyroxenite) as a fluxing agent for pelletisation — and this is a global first. To protect the intellectual property right, a patent has been filed for this innovation. Also, a paper on the innovation has been published in the International Journal of Mineral Processing.
Other benefits include a 30-percent increase in pellet strength and a 4-percent decrease in the generation of fines. Just as significant, the fuel consumption in the blast furnace has decreased (by 29 kg/tonne of hot metal), thus securing savings in natural resources and a reduction of carbon emissions.
Orex group through their Joint Venture partners Lootah group has developed high MgO Pyroxenite with a dedicated production line and feedstock mining area to maintain quality standards required for pellet production. Our present capacity is 2,500 MT/day.
BENEFITS OF PYROXENITE
Dolomite consumption is 100 Kg/ ton in blast furnace and 50 kg/ton in Sinter plant. With introduction of Pyroxenite, Dolomite consumption would be stopped in blast furnace.
Direct benefits of pyroxenite same MgO and high silica as Dolomite are as follows.
​
-
Replacement of dolomite in blast furnace.
-
Reduction in coke consumption to the tune of 5 kg/ ton. Present consumption 58-60 kg/ton which shall be reduced to 53- 55 Kg/ ton on using Pyroxenite.
-
Increase in productivity by 2-4 %.
-
Decrease of quartzite in blast furnace.
-
Decrease in crushing and handling cost of dolomite.
The tailor-made dual flux, developed through thermodynamic modelling, works well for a wide variety of iron-ore fines. The innovation resulted in a 12-percent increase in the productivity of the pellet plant (from 17.6 tonnes/m2/day to 19.7 tonnes/m2/day), which translates into an expected saving of Rs5.3 billion over the next two years.

Just as significant, the fuel consumption in the blast furnace has decreased (by 29 kg/tonne of hot metal), thus securing savings in natural resources and a reduction of carbon emissions.
