Manganese ore tailing: Optimization of acid leaching

Jan 01, 2015 Microbeads of chitosan were tested for removal of leachate acidity and recovering of soluble manganese. Manganese recovery from the leachate was 95.4%. Upon drying the leachate, a solid containing mostly manganese sulfate was obtained, showing that the proposed optimized method is efficient for manganese recovery from ore tailings.

Jan 06, 2020 The country, which is believed to have the fourth-largest manganese reserves, produces 15% of the globe’s manganese ore and has 11% of the world’s economic demonstrated resources of the ore. Australia has three mines and one tailings re-treatment plant.

High increase in biodegradability of coking wastewater

Jun 27, 2020 When Fenton + O3/Mn ore tailings were used to pre-treat the raw water, the biodegradability (BOD5/COD) of the wastewater was increased to 0.54. It is proved that the combined process Fenton + O3/Mn ore tailings has better performance than the ordinary single advanced oxidation process.
