flowchart for the formation of gold

  • Colloidal gold Wikipedia

    The formation of gold nanoparticles comprises three main steps: reduction of gold salt ion by block copolymers in the solution and formation of gold clusters, adsorption of block copolymers on gold clusters and further reduction of gold salt ions on the surfaces of these gold clusters for the growth of gold particles in steps, and finally its stabilization by block copolymers.

    The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed.

  • Gold processing Mining and concentrating Britannica

    In cyanidation, metallic gold is oxidized and dissolved in an alkaline cyanide solution. The oxidant employed is atmospheric oxygen, which, in the presence of an aqueous solution of sodium cyanide, causes the dissolution of gold and the formation of sodium cyanoaurite and sodium hydroxide, according to the so-called Elsner reaction:

    Two sub-processes that are a part of lithification are compaction and cementation. Compaction is the compression of the sediments under overlying weight of sediments. Cementation is the process of filling in the gaps in sediments, with minerals that gel them together. Crystal formation may occur here too.
