For more than 30 years Tall Bennett has supplied a range of flotation reagents including collectors and depressants to the Mining Industry in Australia and nearby countries, with involvement ranging from very early trial work on new projects to simple replacement of existing reagents to achieve lower costs. The company is prepared to undertake trial work on significant projects which may not be likely to come to fruition until some years in the future. Where in-house technical capability is not able to handle complex metallurgical questions which arise from time to time, consultants, both from Australia and overseas, are employed to collaborate on these issues.

Base metal sulphide deposits are the main area of our traditional work. A number of Mining Laboratories around Australia are well acquainted with the Tall Bennett range of collectors and are familiar with the significant improvements in grade/recovery which these products can achieve. Products include collectors such as Dithiophosphates, Thionocarbamates, Mercaptans, Specialty Xanthates, and depressants including Carboxymethyl cellulose and Guar gums etc. New technical work at overseas sites and research establishments is constantly monitored to seek more effective molecules than those presently being used and results in an ever improving product range. Collectors designed specifically for each site is a normal part of our role in optimising flotation performance.

An important part of the service offered is provision of ongoing technical assistance to those projects which are users of Tall Bennett reagents. This usually takes the form of visits by consultant laboratories (at our expense) designed to support the existing products and to determine what further improvements might be possible in each circuit.
