Image processing technology has been successfully applied to fault detection of copper flotation processes, and the key to realize image processing based fault condition recognition is accurately extracting froth image features closely related to key production indices. To extract texture features of froth images in real-time, a multi-scale gray level co-occurrence matrix (M-GLCM) method is pro...

Copper(II) forms 1:1 and 1:2 intense red complexes with phenanthraquinone monophenylthiosemicarbazone (PPT) at pH 3-3.5 and > or =6.5, respectively. These complexes exhibit maximal absorbance at 545 and 517 nm, the molar absorptivity being 2.3 x 10(4) and 4.8 x 10(4) l mol(-1) cm(-1), respectively. However, the 1:1 complex was quantitatively floated with oleic acid (HOL) surfactant in the pH ra...

The Wushan Operation has been studied as a case study, particularly relevant to the copper-molybdenum separation circuit, in which efforts have made improve quality of molybdenum concentrate through diagnostic analysis. A key finding appearance coarser silicate minerals due their inadvertent activation flotation. suitable flotation conditions occurs, most likely, upstream bulk regarding usage n...

This study provides an up to date review of tannins, specifically quebracho, in mineral processing and metallurgical processes. Quebracho is a highly useful reagent in many flotation applications, acting as both a depressant and a dispersant. Three different types of quebracho are mentioned in this study; quebracho “S” or Tupasol ATO, quebracho “O” or Tupafin ATO, and quebracho “A” or Silvafloc...

Reuse of process water in the flotation sulfide ores has crucial importance for environmental sustainability and improved economy. However, chemistry may be a critical subject efficiency as dissolved ion concentration increases with reuse. In this study, effects reuse on Cu-Zn ore were investigated. The flowsheet consists pre-flotation section to remove naturally floatable talc particles, seque...
