Activation mechanism of lead ion in the flotation of stibnite
Apr 01, 2018 The flotation results from Figs. 4 and 5 demonstrate that Pb(NO 3) 2 is a superior activator for stibnite flotation with BX at a pH of 6.5. 3.2. ICP-MS study. It was reported that the substitution of Pb 2+ for Sb 3+ at the stibnite surface could occur during stibnite flotation (Solozhenkin et al., 1991). This substitution process may lead to a
Activation mechanism of lead ion in the flotation of stibnite
The flotation of stibnite with Pb 2+ as an activator was examined with micro-flotation tests, inductively coupled plasma mass spectrometry (ICP-MS) experiments and density functional theory (DFT) calculations. It was found that at a pH of 6.5, the addition of Pb(NO 3) 2 notably improved the flotation efficiency of stibnite with butyl xanthate (BX). At a pH of 6.5, Pb 2+ was the dominant

Bulk flotation followed by sequential flotation of gold-bearing sulfides, and depression of stibnite. This method was practised at the Bradly concentrator (USA) and consisted of the following steps: first, bulk flotation of stibnite and gold bearing sulfides at pH 6.5 using lead nitrate (Sb activator) and xanthate; second, the bulk concentrate is reground in the presence of NaOH (pH 10.5) and

Froth flotation method for stibnite Engelhard Minerals
I claim: 1. A froth flotation process for recovering stibnite from an ore, ore concentrate or ore preconcentrate containing iron sulfide minerals using acidic, recirculated or mine water containing sulfate salts of heavy metals and alkaline earth metals to form the flotation pulp, said water not having undergone conventional water treatment intended to render the water neutral and to remove
Flotation Reagents 911 Metallurgist
Jun 08, 2016 Stibnite, the antimony sulphide mineral, responds much better to flotation after being activated with lead nitrate. The theory generally accepted on activation is that the activating substance, generally a metallic salt, reacts with the mineral surface to form on it a new surface more favorable to the action of a promoter.
Metal Extraction Process for High Grade Stibnite of Kharan
Stibnite ore of Kharan is a high grade ore and it contains 66% antimony sulfide as confirmed by X-ray diffraction (XRD) analysis. Therefore, up-gradation through froth-flotation is not required and instead of using concentrate the ore is employed directly for extraction of antimony metal as its recovery is better by iron precipitation since
