The difference in cost of 48%Mn ore Lumps & 48%Mn sintered concentrate = 11000-10325 = Rs.675/T. The main purpose of this paper is to show that establishment of beneficiation unit & Sintering unit is economically feasible. There are many misconcepts, still Increased demand for manganese alloys and compounds for various industries created a dire need of Manganese (Mn) ore beneficiation technology.

During mining, beneficiation and transportation of these manganese-bearing ores up to 30% of the ore produced is converted into −10 mm low grade Mn ore fines. Indian manganese ore deposits occur as bedded sedimentary deposits and found in Madhya Pradesh, Maharashtra, Gujarat, Andra Pradesh and Orissa states.In the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO2, with a manganese-to-iron mass ratio (Mn:Fe ratio) of 1.6. This ore was characterized in detail using different Effect of desliming on the magnetic separation of low-grade

The sample used in the experiments is a low-grade manganese ore from Indonesia, and the inductively coupled plasma atomic emission spectrometry (ICP-AES, model Optima-7000DV) analysis is presented in Table 1.The contents of calcium and manganese in the ore are 27.3 wt% and 16.4 wt%.Siliceous manganese ore, associated with the banded iron formation occurs in large volume in northern Odisha, India. It is a sub-grade ore containing 21% Mn, 60% SiO 2 and 3% Fe, hence do not find any use and considered as waste.

In 2019, Australia's manganese ore production totalled approximately 7.5 Mt (Table 2; Table 3). The total tonnage of manganese ore mined is approximately twice the tonnage produced because of yields of around 50% after beneficiation. Export data for Australia's manganese products, including manganese ore, were not available.Capacity is 5 T/hr or 10 T/hr. When applied to low grade high silica Iron ores Iron content has been found to be enhanced by 8 to 10 % from 48% to 58 %, with overall wt. recovery of 60 to 70 %. Recently this technique was applied to low grade siliceous Mn ore with very encouraging results.

In both cases there was sufficient evidence for correlation, depending on the mineralogy, between the Mn and Fe grades of the ore and the final concentrate grade and Mn/Fe ratio. To yield a concentrate suitable for use in ferromanganese production, it is recommended that the ore contain a minimum initial concentration of ∼25% Mn and ∼10% Fe.Abstract In this study, the use of XRF, XRD and other instruments found that the manganese content in the ore was 14.53%, and the main forms were carbonate, iron manganese oxide and manganese oxide. Because of the special magnetic susceptibility of these minerals, the magnetic separation method was chosen to improve the grade of Insight into Mineralogy of a Low-Grade Manganese Ore for
