May 16, 2016 Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary ...

The cold cyanide soak prior to elution of about 1 hour 1% cyanide is a good start- this is followed by a cold rinse--BUT-- the rinsed solution must be kept out of the circuit - about four bed volumes of rinse will remove most of the soluble copper on the carbon- we used to spray that water on old heap leach pads and active cyanide broke down there leaving copper behind to a large degree where ...
Waxing . Copper blocks can be turned into the respective waxed copper blocks by using a honeycomb item on them.. Scraping .

After your piece is clean then wash in distilled water for an equal amount of time that the specimen was in the solution. Then in running (or regularly changed) tap water. Apparently the solution works by reducing Fe3 to Fe2 and then dissolving Fe2 in the Citric Acid.
Take that and smelt it in the furnace. So, 9 iron ore that is first macerated into 18 crushed iron ore then washed will become 18 purified crushed iron ore, 36 tiny piles of iron dust, and 18 stone dust. Which results to 22 iron bars which is 4 more and a total of 13 more than standard smelting but at
