Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu -Fe sulphide ore. CuSO 4 solution can also be used for removing Pb, Zn, and Fe from copper sulphide ores. In presence of oxidizing agents: Ferric ion: Ferric sulphate or chloride react with metal sulphides liberating elemental sulphur, e.g.
Carlin-Type Gold Deposits in Nevada: 2003), other significant Au, Ag, Pb, Zn, or Cu deposits (crosses; Long et al., 2000), eastern limit of the Roberts Mountain allochthon (bold white line; Crafford and Grauch, 2002), cities (small circles), and highways FIG. 2. Ore grade (g/t Au) vs. metric tons of ore for Carlin-type deposits (small
The ore in both reduced and oxidized types tends to have low Cu:Au (<2000), Cu:Ag (<1000), Zn:Au (<100) and Ag/Au (<1) ratios. Gold is commonly present as micron-sized inclusions in sulphides, or at sulphide grain boundaries. It is often associated with tellurides. To the naked eye, Au skarn ore is generally indistinguishable from waste rock.
This month five new VMS Zn-Pb-Cu-Ag-Au ore CRMs have been released (OREAS 620 series our catalogue has been updated to include these new CRMs). The release of six new carbonatite-hosted REE ore CRMs is imminent. A suite of four Cu-Au oxide ore CRMs will follow in early May.

Mining in Austria is an industry on the decline.. After a period of postwar expansion, mineral production has stagnated in recent decades, and metals mining continues to decline, because of high operating costs, increased foreign competition, low ore grades, and environmental problems.
An ore is a mineral which has a metal inside it. Ores are usually extracted by being mined.They can sometimes be found on the Earth's surface. The metal in ore is often valuable. There are different ways to get the metal out of the ore.
