Combined inhibitory effect of calcium hypochlorite and dextrin on flotation behavior of pyrite and galena sulphides

, 2020
Selective separation of pyrite from base minerals is very important and challenging. This research investigates the combined inhibitory effect of two novel reagents on flotation behaviors of pyrite and galena under the low alkaline conditions.

The selective flotation of chalcopyrite against galena using alginate as a depressant

Minerals Engineering, 2019
In this paper, sodium alginate was put forward as a flotation depressant for selectively separating the chalcopyrite from galena. The effects of the sodium alginate on the flotation performance of chalcopyrite and galena were studied using ammonium ...

Synthesis of a novel collector based on selective nitrogen coordination for improved separation of galena and sphalerite against pyrite

, 2020
During the separation of sulfide minerals, the problem of low selectivity always arises. A novel thiadiazole derivative (CSC-1) was developed for the flotation of sulfide minerals.

Caves in the Galena Formation

The Journal of Geology, 1938
The cave systems commonly are reticulated patterns, faithful delineations of the joint system of the formation, with no integration toward a trellised subterranean drainage pattern. The distribution of the lead and zinc ores gives no indication of any former lower water table.
