gold ore and sorter of metals

Gold Ore Sorting : TOMRA

Gold ores are typically amenable to sensor-based ore sorting to some degree, and this is usually accomplished with XRT or laser sensors, or a combination of both. A two-step sorting flow-sheet consisting of an XRT rougher plus a laser scavenger (or alternatively, a laser rougher and an XRT scavenger) has already proved an optimal recovery

Gold Properties, occurrences, and uses Britannica

Gold Gold Properties, occurrences, and uses: Gold is one of the densest of all metals. It is a good conductor of heat and electricity. It is also soft and the most malleable and ductile of the elements; an ounce (28 grams) can be beaten out to 187 square feet (about 17 square metres) in extremely thin sheets called gold leaf. Because gold is visually pleasing and workable and does not

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

Normally even good, rich gold ore has no gold metal which is visible to the naked eye. The photo at left shows small particles of metallic gold in quartz taken from the mountains of Canada. Sections of gray colored quartz in the specimen have this appearance because of the finely disbursed sulfide crystals present in this ore.

Geology of Gold Mineralization & How Gold Deposits are Formed

Deposits of this type are mined for the predominant metals, but the gold is also recovered as a byproduct during processing of the ore. Most byproduct gold has come from porphyry deposits, which are so large that even though they contain only a small amount of gold per ton of ore, so much rock is mined that a substantial amount of gold is
