The chrome ore is transported in a secure and efficient city to Pakistan's modern and well developed Ports. Railway Cargo service also connects Jijal Complex to the Ports.
MLA is currently the world's most advanced mineral automatic analysis instrument. Samples of fines were tested through MLA 650 mineral automatic detection system, results in Figs. 2 and 3 showed that the main mineral compositions are chromite, chlorite and forsterite. Table 1 shows that a total of 13,011 particles in the sample were …

Chromite is the only ore of chromium, a metal essential for making stainless steel, nichrome, chrome plating, pigments, refractories, chemicals and pharmaceuticals.
It is found that the removal rate of hard-to-grind minerals in steel slag is the highest when steel slag enters magnetic separation particle size of 1 mm and magnetic field strength of 1400 Gs. Compared with untreated steel slag, the grinding efficiency of treated steel slag can be increased by 22%, and the hydration activity is not affected.
Supply of world chromite (chrome ore) has come under severe pressure over the past year driven by strong demand for ferrochrome used in ferroalloy production for …
Addressing challenges inherent in Ferro Chrome recovery necessitates a meticulous and strategic approach to optimize metal extraction efficiency from slag in the ferrochrome industry of South Africa. The recovery processes in ferroalloy plants face obstacles such as metal loss in slag, requiring the implementation of efficient recovery …
the mid-1990s. This technology was used for the different hard rock minerals, i.e., copper, gold, and platinum ore. Recently introduced, HPGRs have high energy and grinding efficiency [8], improved mineral liberation [10], particle weakening [13], and generation when compared with conventional crushers in the mineral industry. …
3. Limonite Flotation process. Limonite has a complex structure consisting of hydrated iron oxides. The flotation method is unique in its ability to selectively separate the desired minerals from the unwanted gangue material using surfactants, thereby improving the overall efficiency of ore processing. Flotation involves the addition of reagents to …
The most important chromium-bearing phases in the Earth's upper mantle are chrome spinel, Cr-bearing pyroxene, and Knr-garnet, which are replaced with Knr-Maj garnet, MgCr 2 O 4 with the calcium titanate-type structure, and (Mg,Fe) 2 SiO 4 wadsleyite/ringwoodite.
