  • Introduction to Gold Nanoparticle Characterization

    DLS measurements of gold nanoparticles is a very sensitive technique and can be applied not only to measure the size of particles, characterizing surface modification, monitoring the stability of gold nanoparticles over a period of time, but also as a detection approach for bioassays.

  • Gold extractionWikipedia

    Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.
