    Gold Extraction

    Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution mineral processing hydrometallurgical and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing resulting in direct recovery of

    Physical Methods. The most powerful physical technique for separation of gases is mass spectrometry described in Chapter 23 though only minute quantities can be handled in that way. Gases may also be separated by diffusion for example hydrogen may be removed from a gas stream by allowing it to diffuse through a heated tube of gold

    Oct 16 2019nbsp018332Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in sie to be captured with a porous material. Particle sie can vary considerably given the type of mixture.For instance stream water is a mixture that contains naturally occurring biological organisms like bacteria viruses and protooans.

    A mixture can contain solids liquids andor gases. The components in a mixture are not chemically joined they are just mixed. That means we do not need to use chemical reactions to separate them. Mixtures can be separated using physical methods alone and that is what this chapter is all about how to separate mixtures.

    How Gold Is Made

    Gold recogniable by its yellowish cast is one of the oldest metals used by humans. As far back as the Neolithic period humans have collected gold from stream beds and the actual mining of gold can be traced as far back as 3500 B.C. when early Egyptians the Sumerian culture of Mesopotamia used mined gold to craft elaborate jewelry religious artifacts and utensils such as goblets.
