Oct 05, 2012 The troubles one has to go through to make money. The ore concentrate is really valuable, its got a lot of Iron in it 76% which makes it good for the leach I use for processing it. As the Iron goes into solution the gold, silver, Pd, Pt, salts go into the solution as well.
One of the highest grade silver ore specimens I saw was from Australia, and it truly glittered (almost 100 ounces per ton). Very High Grade Oxide Gold Ore, Assay 5-15 Oz/Ton When one locates a promising vein or mineralized formation that may be ore (as opposed to rock), the next step is to take some samples of the formation.

Dec 23, 2018 High-grade gold contained in narrow veins that snake through the rock can only be mined by excavating shafts and hoisting the ore to surface via low tunnels (drifts).
May 15, 2021 When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore …
The reasons of gold refractory, ore classification, and preprocessing methods. I.The reason of the gold mineral refractory. There are so many types of reasons that caused the difficulty of gold ore processing, including physical element, chemical element, and mineralogical element.
The Yanacocha Gold Mill processes high-grade gold ore to produce a gold-bearing solution for treatment at the La Quinua processing plant. The Yanacocha Gold Mill processes between 5.5 and 6.0 million tonnes per year. Production: Commodity Units 2021 2020 2019 2018 2017 2016 2015; Gold:
Jan 02, 2013 The carbon-in-pulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid.
This is very high grade gold ore from the Cripple Creek district in Colorado. Many old time miners mistook this type of mineral for low grade sulfides, but this silvery metallic material probably is 40 percent gold …
Silver processing, preparation of the ore for use in various products.. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000 ...

First, it allows keeping the grade of the plant feed in over 95% of the time within the target range. Second, it enables meeting operational targets on throughput and utilization, since it decouples crushing and ore processing. Overall, it turned out to be financially advantageous to set up the process with a coarse ore stockpile.
For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let’s assume that gold is valued at $1500 per ounce.
0.5–1.5 g/t gold is average grade; Over 1.5 g/t gold is high grade Underground: 0–5.0 g/t gold is low grade; 5.0–8.0 g/t gold is average grade; Over 8.0 g/t gold is high grade; Gold measured in ounces per tonne is “bonanza” grade. Silver. Open pit: 0–30 g/t silver is low grade; 30–150 g/t silver is average grade; Over 150 g/t silver is high grade Underground:
Feb 07, 2020 When gold ore has a high grade, it takes relatively less effort to extract an ounce of gold from the ground and, since less ore has to be dug out, it reduces the input costs for the gold mining ...
Jul 14, 2016 Gold Leaching & Processing of Arsenic Ore ... South Africa, where a refractory high-antimony gold ore is being treated, flotation and cyanidation of the flotation concentrates and tailings are being practiced. The association of the antimony and gold is very intimate, and during 1946, while the antimony recovery amounted to 70.6 per cent, only ...
May 26, 2021 The grade of mined, raw gold ore is measured in grams of gold per tonne of ore. High grade gold ore contains more gold per tonne; this means that more gold is obtained from every tonne mined. This greatly increases the profitability of a mine. Indeed, the high cost of processing extremely low grade ore may actually make mining financially unfeasible.
With ores of higher gold content (i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.
