Currently controlling dosage in mineral flotation process is based on the subject experiences of operators, which are influenced by different operating technique. According to different shifts, process performance of forth flotation is different so that the flotation process is often running in unstable states. Lots of production data of gold and antimony forth flotation …

202367 · Antimony Metallurgy. Antimony metallurgy is the technology that extracts antimony metal from antimony ores or produces antimony compounds. Antimony was discovered in the ancient time, and its name was derived from antimonite. In 1604, a process was invented to extract antimony and antimony sulfide as described by B. Valentine of …

The effects of Mn2+ on the flotation behaviour of fine refractory antimony oxide and its flotation separation from silicified limestone were studied. The principal gangue mineral, under the condition of pH=7.5 and in the presence of modified water glass through flotability test, measurements of interfacial potential and adsorption, and X-ray diffraction technique …

Due to the low antimony (5.06%Sb) and the high Arsenic (1.38%As) content, it is an important requirement to increase the Sb content of this ore by flotation, as well as to reduce the As content to certain levels. Stibnite as an antimony mineral and arsenopyrite as arsenic mineral, are minerals that have a sulphurous structure in mineralization ...

201796 · The content of antimony in the crust is only about 0.0001%. Globally, antimony ore resources are widely distributed over all continents, except Antarctica. However, the main antimony ore producing countries are China, Russia, and South Africa [10]. China’s antimony reserves and production rank first in the world. Its antimony …

An investigation is made of the diffusion of antimony through the bulk and along grain boundaries in copper bicrystals containing a symmetric 〈100〉 misorientation boundary with misorientation angles from 20 to 37.2°. The bicrystals are grown by the method of horizontal zone recrystallization. The temperature range for these studies is 480–580 °C, …

The copper flotation process design is a multi label learning. Before multi label classification and regression, label-specific features for each label need to be selected from the original features. This paper puts forward a multi label feature selection (MLFS) based on domain knowledge and label correlation. In the proposed MLFS, the domain knowledge function …
