What ore is gold found in? Quora
Gold ore is simply minerals, gravel or dirt that contain gold as part of their makeup. Gold is extracted from gold bearing ore. Gold can run in veins within a rock matrix, sometimes quartz, but not exclusively. It can be powderized into sand and dirt deposits placed by erosion.

In What Rock Formations Can Gold Be Found? Sciencing
Apr 24, 2017Alluvium is a deposit of eroded materials and sediment that is gathered into one area. As gold and other materials are eroded, the small pieces are pushed by water and other forces into creek and river beds and other depressions. Because gold is heavier than most other naturally occurring materials, it settles at the bottom of these deposits.

Minerals with Iron Which Minerals Have the Most
Iron ore, or iron rock, is the host rock in which iron rich minerals can be extracted. The most commonly extracted minerals within iron ore are magnetite, hematite, goethite, and siderite. Iron is most commonly extracted from the iron rock by way of blast furnace at very high temperatures. Iron ores can contain oxide and other impurities.

Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore

Gold extraction Wikipedia
A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold particles, making it difficult for the leach solution to form a complex with the gold. Organic carbon present in gold ore may adsorb dissolved gold-cyanide complexes in much the same way as activated carbon.

Use of Magnetite as an Ore of Iron. Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Twenty-Five Gold Indicators You Should Know ICMJ
Gold-bearing veins can consist of calcite or mostly sulfides—which often weather into iron-stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators. Iron-stained ground areas and gossans are basically another sort of color change in the ground surface.
