Flotation. Our specialists have a comprehensive range of skills in flotation circuits. Our extensive experience incorporates all types of conventional, column, and novel flotation equipment. This covers a diverse range of projects with concentrators operating at 240,000 tpd or more, involving a full range of base and precious metals and minerals.
This requirement needs to be balanced by the cost of grinding finer and the revenue that results from an increase in grinding throughput, which often results in a coarsening of the flotation feed. A relationship can be developed between grind size and flotation recovery using modelling techniques.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

For more than a century now, flotation has been at the heart of the mineral processing industry. In this month's SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.
Mining and minerals processing equipment and infrastructure are used to target sustainable outcomes through environmental research. From in-house services such as mineral sample analysis and preparation to field equipment such as UAVs and vehicles, the University of Queensland can fulfil your mining and minerals processing needs.
Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment.
Flotation for Treating Sulphide Ores at a Coarser Grind Massimiliano Zanin1, Bellson Awatey1 and Jaisen Kohmuench2 1. University of South Australia 2. Eriez Flotation Division, USA ABSTRACT Fluidised-bed flotation emerged in the last 15 years as a promising technology for the flotation of minerals at a much coarser particle size.
The mine at the Endeavour 26 ore body, the largest at Northparkes, had pre-mining reserves of around 50 million tons at grade 1.4% copper and 0.4g/t gold. Total proven and probable reserves for copper are approximately 56 million tons at a grade of 1.1%. Mining. Northparkes supports two open pits and a block-cave underground mine.
