  • Gold extraction process

    Gold fingers are the goldplated columns that you see along the connecting edges of printed circuit boards (PCBs). The purpose of gold fingers is to connect a secondary PCB to the motherboard of a computer. PCB gold fingers are also used in various other devices that communicate via digital signals such as smartphones and smartwatches.

  • How Gold Is Mined Gold Mining Process World Gold Council

    Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted significant exploration and development needs to take place both to determine as accurately as possible the size of the deposit as well as how to extract and process the ore efficiently safely and responsibly.

    How Gold Works. To isolate pure gold mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravellike material then enters rotating drums filled with steel balls.

  • How Is Gold Extracted From Gold Ore? Sciencing

    Cyanide. Yet another gold removal process is flotation.The ground ore is put into a solution that contains a frothing agent along with a collecting agent and organic chemicals. The frothing agent turns the solution into a foam. The collecting agent bonds to the gold creating an oily film that will later attach itself to the surface of air bubbles.

    The Chemistry of the Extraction of Gold SAIMM

    THE CHEMISTRY OF THE EXTRACTION OF GOLD Cu(CN) and Cu(CN)!. The insoluble gold cyanide compound AuCN precipitates from acidic solutions of aurocyanide ions as follows Au(CN) + H+ = AuCN + HCN. (15.2) This reaction takes place readily in strongly acidic solution and slowly in weak acid solutions (pH 2 to 3).
