HLS tests were performed on a fresh metallurgical composite labelled as BG2 with feed grade of 1.17-1.40% Li 2 O. The sample for the tests were prepared by size reduction of the bulk composite to pass 12.7 mm. Several individual size fractions were separated from the minus 12.7 mm composite to be used for the heavy liquids testing.

Statistics: An introduction to sample size calculations

Statistics: An introduction to sample size calculations Rosie Cornish. 2006. 1 Introduction One crucial aspect of study design is deciding how big your sample should be. If you increase your sample size you increase the precision of your estimates, which means that, for any given estimate / size of effect, the greater the sample size the more “statistically significant” the result will ...

Heavy Liquid Separation - ALS

HLS for Iron Ore characterization Data derived from HLS tests on iron ores is chiefly used for ore characteristion and process design. Typically, samples are screened into a range of size fractions prior to testing, for example: ••–6.3 + 2mm ••–2 + 0.5mm ••–0.5mm + 0.045mm Each size fraction is then separated into a range of ...

Modern gold deportment studies - SGS

The result of the HLS gives an indication of the amenability of the ore to gravity recovery. However, since the sample must be deslimed for HLS to be effective, a certain proportion of the gold that would be amenable to gravity separation (grains >10 µm in size) might report to the slimes fraction and not to the HLS
