On-line analysis of the stability and other features of froths and foams by use of digital image processing
(Stellenbosch : Stellenbosch University, 2002-03)
ENGLISH ABSTRACT: The objective of this study is the assessment of the usefulness of an industrial
machine vision system for laboratory studies of especially flotation froths and other
foams. With this in mind it was ...
Monitoring of froth systems using principal component analysis
(Stellenbosch : Stellenbosch University, 2002-04)
ENGLISH ABSTRACT: Flotation is notorious for its susceptibility to process upsets and consequently its poor
performance, making successful flotation control systems an elusive goal. The control of
industrial flotation ...
Estimation of concentrate grade in platinum flotation based on froth image analysis
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Flotation is an important processing step in the mineral processing industry wherein valuable minerals
are extracted. Flotation is a difficult process to control due to its complexity, meaning that the ...
Scale-up of mechanically agitated flotation processes based on the principles of dimensional similitude
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The use of dimensional analysis to scale-up mechanically agitated flotation processes
and to identify deficiencies in froth flotation plants was explored. The full range of
operating variables was ...
