Beneficiation of a Low Grade Limestone by Flotation Column

electrostatic interaction [4]. The cationic flotation (reverse flotation) is attractive because the cationic collectors are insensitive towards hard water salts, low consumption, less induction time and high contact angles. 2. Materials and Methods The beneficiation study of limestone was carried out for low-grade limestone from a small Mine,

Collector dosage variation: Inverse flotation tests were conducted at D80 size of 120 microns, varying collector SOKEM 565C dosage from 0.4, 0.6,0.8 and 1 kg/t. The results are shown in Table 4. From the experimental studies, it has been observe that an increase in collector dosage reduced the yield and silica content in the non float.

Beneficiation of a low grade limestone sample - ScienceDirect

A 0.5 m diameter flotation column was commissioned at a mine site in Sankagiri, Salem district, Tamilnadu, India, to study the beneficiation of low grade limestone. The salient features of the column are: (1) Column: The column shell is made of mild steel and has several flanged sections of various lengths.
