Selective adsorption of a high-performance depressant onto dolomite causing effective flotation separation of magnesite from dolomite.
TL;DR: HEDP could be used as a high-performance depressant for the dolomite flotation to realize the decalcification of the magnesiteFlotation, resulting in a significant difference in the flotation performances of the two minerals.

The role of surface roughness in the wettability and floatability of quartz particles
TL;DR: In this paper, the role of surface roughness in quartz flotation was investigated through measurements of X-ray photoelectron spectroscopy (XPS), Scanning Electron Microscope-Energy Dispersive Spectrometry (SEM-EDS), collector adsorption capacity and contact angle analysis.

A new model for the degree of entrainment in froth flotation based on mineral particle characteristics
Bin Yang,Wanzhong Yin,Zhanglei Zhu,Donghui Wang,Han Huili,Yafeng Fu,Haoran Sun,Fudong Chu,Jin Yao +8 more
TL;DR: In this paper, a new model related to the particle shape for predicting the degree of entrainment of gangue minerals with different particle characteristics, specifically different particle shapes, was proposed based on the settling velocity.

New insights into the dispersion mechanism of citric acid for enhancing the flotation separation of fine siderite from hematite and quartz
TL;DR: In this article , citric acid was employed as a specialized dispersant to eliminate the strong heterocoagulation of fine siderite with hematite or quartz, which resulted in an increase in the kinetic selectivity index.
