Parametric Optimization in Rougher Flotation Performance

Parametric Optimization in Rougher Flotation Performance

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.

EJ204 Subaru Engine

EJ204 Subaru Engine

The Subaru EJ204 was a 2.0litre horizontallyopposed (or 'boxer') fourcylinder petrol engine with double overhead camshafts. The naturally aspirated E204 engine was initially introduced in the 2005 Subaru GD/GG Impreza and 2006 Subaru BL/BP Liberty as a more powerful alternative to the single overhead cam EJ202 engine, but effectively replaced the EJ202 when the GE/GH

Aug 15, 2018· Microflotation tests were conducted in a mechanical agitation flotation machine with a 40 ml cell. The mixture was stirred at 1650 r.p.m. by a fourbladed impeller. In each test, 2.0 g of pure cassiterite particles were dispersed in the cell with 30 ml distilled water for 1 min. The pH was adjusted by adding a pH regulator for 3 min.
