Optimization of reagent dosages for copper flotation using

The effects of Z11 and AP407 collectors as well as AF65 and AF70 frothers were evaluated in the rougher flotation circuit of the Sungun copper concentrator plant using 2 4 full factorial design. Response functions were produced for both Cu grade and recovery and optimized within the experimental range. The optimum reagent dosages were found to be 12.01 g/t Z11, 11 g/t AP407, 3 g/t AF65 and 5 g

Assay Optimization and Validation Sigma-Aldrich

Primer optimization using T a. A) A range of annealing temperatures was tested for identical reactions. Annealing at 64.8 °C and 61.7 °C results in identical C q values and high reproducibility between replicates, but the slightly lower temperature produced a higher yield of product. B) Two identical reactions were set up in different reagent mixes (LuminoCt ® SYBR ® Green qPCR ReadyMix
