A low grade graphite run-of-mine (r.o.m) ore from eastern India was studied for its amenability to beneficiation by flotation technique. The petrography studies indicate that the ore primarily consists of quartz and graphite with minor quantity of mica. It …
Keywords: Low grade iron ore, mineralogy, jigging, particle size, water rate, separation efficiency. 1. INTRODUCTION Large numbers of iron ore mines are in operation in Orissa, India to meet the internal and export demand of iron ore for iron and steel making. During the process of
Low grade graphite ore forms the bulk of these deposits, which needs to be beneficiated [1,2]. Crystallinity, flake size and the relationship of graphite with the associated …
Low grade graphite ore containing 14-15% fixed carbon (F.C) from Tamilnadu Minerals Limited (TAMIN) have been investigated for beneficiation. It responds well to the flotation technique. The existing graphite beneficiation plant has the capacity to process 200 tons of ore per day to yield graphite concentrate with fixed carbon content of 84 to 96% purity and recovery of 80 to 88 %.
The Shodhganga@INFLIBNET Centre provides a platform for research students to deposit their Ph.D. theses and make it available to the entire scholarly community in open access.

for mining based on the characteristics and depth of phosphate ore [4]. Similarly, to concentrate low-grade phosphate ore to a marketable grade (~30% P2O5) [5] several pre-processing and processing methods are defined [1,6,7]. These are based on the ore type, associated gangue minerals and the amount of impurities,
sive deposit of low grade graphite ore, containing 10-17% graphitic carbon, has been found which can be exploited on commercial scale. This paper deals with the beneficiation study of the said graphite deposit using froth floatation technique. Chemical analysis was carried out by conventional gravimetric and volumetric methods.
A low grade graphite run-of-mine (r.o.m) ore from eastern India was studied for its amenability to beneficiation by flotation technique. The petrography studies indicate that the ore primarily …
Grades up to 40% carbon were found. Gangue minerals in the ore are quartz, plagioclase, K-feldspar, biotite and orthopyroxene. Some of the largest ore bodies contain about 250,000 tonnes each with an average grade of 20% carbon. Bench-scale beneficiation tests shown that the ore can be upgraded to a maximum grade of 97% C, with a recovery of 89%.
The process of extraction of manganese from ferruginous manganese ore using reduction roasting and magnetic separation, beneficiation technology of poor-grade manganese ore to improve the ratio of ...
A low grade graphite ore from eastern India was beneficiated by flotation to improve its quality. The ore was composed of 87.80% ash and 8.59% fixed carbon. Primary coarse wet grinding (d 80: 186 μm) followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate. Regrinding (d 80: 144 μm) of …
