Photos of gold ores, quartz, telluride gold ore and gold

Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent. Get price

Oxidation Zone of Mineral Deposits

The change is caused mainly by the process of oxidative transformation. Metal sulfide ores and deposits of sulfur, salts, and coal undergo the most vigorous change. The metal sulfides are replaced by oxides, hydroxides, carbonates, and sulfates of the same metals. Accumulations of alunite and gypsum form where sulfur is present. Get price

Why is the ore generally converted to an oxide and then

The concentrated ore must be converted into a form which is suitable for reduction. Usually the sulphide ore is converted to oxide before reduction. Oxides are easier to reduce. Thus isolation of metals from concentrated ore involves two major steps viz., (a) conversion to oxide, and (b) reduction of the oxide Get price

Copper Sulfide Ore

Lead oxide ore, mainly in the form of cerussite and anglesite, is originated from primary lead sulfide ore which gradually changed its property under efflorescence and carbonate salt environment. In a lead deposit, lead oxide and lead sulfide usually is detected at the upper layer and lower layer separately. Get price

Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Copper Production in Zambia in Five Easy Steps. How it is

Ore is broken down into smaller pieces. The large pieces of ore are collected by haul trucks and taken to a mill, a large rotating device which makes the pieces smaller through crushing and grinding. There are two types of copper ore (sulphide ore and oxide ore), and each is treated differently in order to liberate the copper inside. Step 3 Get price
