Beneficiation of low grade bentonite clay by chemical methods and their utilisation in oil industries ... Bhavnagar locality ofGujarat for use in oil well drilling. It has been identified that percentage of iron oxide ... grade bentonite clay has become much more as this is 0.1 N HCl
Abstract. Phosphatic clay is a waste material produced during the beneficiation of phosphate ore, which likely poses severe environmental problems. In this study, a phosphatic clay containing 258 ppm of total rare earth elements (REEs) was used as a feedstock for REE recovery. By reacting with 0.1 M HCl at 75 C for 3 h, around 36 % of light REEs and 65 % of heavy REEs were extracted from the raw material
This showed that the use of 1M hydrochloric acid at 70 C can effectively reduce the iron contents in clays with little effect on the crystal structure as indicated by the IR spectrum

The objective of this work is to determine changes of surface properties of a bentonite after acid activation, using hydrochloric acid solutions (HCl) at room temperature. XRD, FX, FTIR, MEB, and BET analyses of the samples have been carried out to examine the structure of bentonite before and after acid activation. It is found that the raw bentonite is composed of dioctahedral montmorillonite

Nov 26, 2015 Malaysia. The plant will produce HPA directly from kaolin clay which will be sourced from the Company’s 100% owned kaolin deposit at Meckering, Western Australia. Altech’s production process will employ conventional “off-the-shelf” plant and equipment to extract HPA using a hydrochloric acid (HCl) leaching process
The kinetics of dissolution of Amazonian metakaolin in hydrochloric acid (HCl) was studied using the ‘Shrinking Core Model’ for spherical and ‘flat plate’ particles of constant size. The Amazonian kaolin was calcined at 700 C for 2 h. The calcined samples (metakaolins) were leached in an HCl solution with 5% excess at 70, 80 and 95
Jun 15, 2021 The extraction of REE using an organic acid, in this case 0.1 M citric acid and 0.5 M trisodium citrate solution, is compared against 0.5 M (NH 4) 2 SO 4, 1 M HCl, 1.2 M H 2 SO 4, and 0.5 M ethylenediaminetetraacetic acid (EDTA). Ashing the coal waste material prior to leaching tests with the citrate solution nominally improved REE extraction
A typical grinder of 45 Mg/hr (50 ton/hr) capacity will discharge about 1.6 to 2.5 dry normal m3/sec (3,500 to 5,500 dscfm) of air containing 1.14 to 11.4 g/dry normal m3 (0.5 to 5.0 gr/dscf) of PM. The air discharged is tramp air, which infiltrates the circulating streams
