    • Microwave heating of gold ores for enhanced grindability

      The faster leaching rate of the microwave processed ore may be attributed to the thermal stress cracking due to differential heating of the individual minerals that make up the ore. Micro cracking as observed in Fig. 3 increased the ease of access of leaching reagent to the mineral of interest and consequently, gold leaching was enhanced. In a

      Shawn Pure gold is not magnetic. That is, it doesnt form a magnet on its own. If you put it in a magnetic field it will magnetize a tiny bit, but only so long as its in the field. and the direction of the magnetizaqtion makes it weakly repel the magnet. There are alloys of gold, for example gold with more than about 20% of the atoms replaced by iron, which do magnetize on their own, at
