Developments in Heavy Construction Equipment

H IST O R Y O F D E V E L O PM E N T An opportunity to discuss the development of any product must include a bit of history so that having observed where we have been one may have a clearer perspective of where we are and may be going. This discussion will try to capture all of these facets. Construction projects of one type or another date back to times before recorded history. M an’s hands we...

Magnetic solvent extraction

4 Solvent Extraction Equilibria

The ability of a solute (inorganic or organic) to distribute itself between an aqueous solution and an immiscible organic solvent has long been applied to separation and purification of solutes either by extraction into the organic phase, leaving undesirable substances in the aqueous phase; or by extraction of the undesirable substances into the organic phase, leaving the desirable solute in th...

Diluent effects in solvent extraction

The fact that the choice of organic diluent is important for a solvent extraction process goes without saying. Several factors, such as e.g. price, flash point, viscosity, polarity etc. each have their place in the planning of a solvent extraction system. This high number of variables makes the lack of compilations concerning diluent effects to an interesting topic. Often the interest for the r...

Contents 1 The Possibility of using Solvent - Solvent Extraction

This report investigates the use of solvent-solvent extraction for the secondary concentration of lead and thorium. The extraction reagents investigated in this report are: For the lead extraction: diethlyammonium diethyldithiocarbamate (DDDC) For the thorium extraction: trioctylphosphinc oxide (TOPO) and di-(2-ethylhexyl)phosphoric add (HDEHP). For all of the extractions 2-octanone was used as...
