Mechanisms of pyrite flotation with xanthates
1991-11-1 The results of pyrite flotation with ethyl xanthate indicate that the formation of ferric dihydroxy ethyl xanthate on pyrite surfaces can either improve or deteriorate the floatability of pyrite, depending on the concentration of ethyl xanthate. Good flotation can be obtained when ethyl xanthate ions and/or diethyl dixanthogen are coadsorbed onget price
Comprehensive Assessment of Flotation Reagents by Their
2022-1-5 Mathematical processing of the experimental kinetics of flotation was carried out by two methods differing in complexity and volume of data. The problem of finding the floatability distribution k (flotation spectrum) on the kinetics of flotation is the problem of inverting the Laplace transform of this distribution .Methods for inverting the Laplace transform were developed in get price

2021-11-1 The hematite and quartz were taken from Huangshi minging Co., Hubei Province, China. The X-ray diffraction (XRD) patterns of these two samples indicate that these two minerals' purities were very high and satisfied to be used for the experiments.The X-ray fluorescence (XRF) further confirms that hematite and quartz have a high grade of 95.32% and 99.78%, respectively.get price

Froth flotation separation of carbon from barium slag:
2021-2-1 The flotation test was conducted to obtain the carbon concentrates, and the parameters including pulp pH, collector dosage (diesel), frother dosage (terpenic oil), and flotation time, were investigated. The optimum froth flotation conditions for the barium slag were identified as pulp pH 8.50, diesel 600 g/t, terpenic oil 500 g/t, and flotationget price

Flotation of Metallurgical Grade Silicon and Silicon Metal
2017-8-24 Flotation experiments performed on metallurgical grade silicon have demonstrated that silicon (Si) can be floated in diluted solutions of hydrogen fluoride (HF) and a frother. The recovery was found to depend on HF conditioning time, frother type, and the concentration of both HF and frother.
