Small-scale cylinder or jar tests are routinely applied to establish the impact of polymer reagents that induce aggregation in mineral systems. Despite their value, such tests are often done poorly or under too narrow a range of conditions, which can lead to trends being either missed or wrongly interpreted. A number of common errors are discussed, together with strategies to maximise the practical value of the results obtained.
