First, the adsorption of two alternative sulphide collectors, DTP-MBT and DTC-MBT, was quantitatively and qualitatively characterized and compared to xanthate at natural and alkaline pH values. The amount of collector adsorbed on mineral surfaces has been measured using UV- visible spectrophotometry and the Beer-Lambert law (Kongolo et al., 2004).

The electrolytic diodes in Roy J Meyers 1913 atmospheric energy harvesting system are probably ideal for electrolytic particle conversion because of how they combine magnetic bias with electrolytic current. But a simple inductive converter like Stubblefield or Hubbard is probably the most efficient and powerful form of particle energy converter.
