Manganese extraction was a function of the carbon content of the medium. Some typical results from leaching Three Kids ore with food-grade molasses are shown in figure 2. After 5 weeks of leaching, 78 pct of the manganese was solubilized from the ore with inoculated 5-pct medium compared to 53 pct manganese extraction with inoculated 3-pct medium.

Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.
