Nether gold ore drops 2-6 gold nuggets when mined with any pickaxe. Fortune has a 33.3% chance to multiply the drops by 2, Fortune II has a 25% chance to multiply the drops by 2 or 3 and Fortune III has a 20% chance each to multiply the drops by 2, 3, or 4 for a maximum possible drop of 24 golden nuggets. The average number of …

Comment by RazerQuick If you're trying to get a lot of copper ore quick at a high level your bags will fill up fast. I ran the Mulgore route for 100 copper dont forget that copper ore only stacks in 10, so I kept stopping at the Venture Co. Mines Cave to smelt ore into bars (stacks in 20) to save space and time.Hope this helps anyone else trying to …

GOLD ORE CHARACTERIZATION The McGill protocol to characterize gravity recoverable gold (GRG) has been presented in Laplante et al. (1). It consists of a progressive (3 stage) liberation and recovery of gold-bearing particles using a laboratory centrifuge unit, which preserves the natural size distribution of gold.

There has also been debate on exactly what constitutes a "coarse" gold ore. And there has been debate on how to pulverise a gold ore containing "coarse" grains of gold without having the gold smear onto the surface of the grinding equipment with the loss of gold. Then there is the problem of assaying a sample before or after pulverisation.

River sand is becoming scarce and meeting the demand of fine aggregates in the construction industry is becoming a challenging task. In this investigation an attempt is made to utilize gold ore tailings as a partial substitute for river sand in producing concrete. River sand is replaced with 5%, 10%, 15%, 20% and 25% gold ore tailings and the …

For example, the assay value of the fine pulp having been found to be $20.00, and the proportion of coarse gold to each assay ton of pulp 1 milligram or $20.67, then the total value per ton of ore in gold would be equal to $20.00 plus $20.67 or $40.67.

The following picture shows the coarse disseminated quartz gold ore from South African, in the picture we can see gold grains clealy, and there are obvious boundary bewteen quartz and gold, of course, they have different specific gravity. For this coarse-grained disseminated gold rock, flotation machine is not the best mineral processing method.

Gold is often classified and labeled according to its size. Various sized pieces of gold are labeled as to their different mesh sizes. "Coarse gold" or "nuggets" are agreed to be any pieces of gold which will not pass through a 10-mesh screen. Medium-sized pieces of gold, flakes and so forth, are of the 10-20 mesh range, of which it ...

Careful management of coarse gold ores is required. It is suggested that laboratories include a "wash" after visibly high-grade (e.g. visible gold-bearing) samples. However, if the ore bears notable coarse gold, then cleaning is best after each sample given that even low-grade samples can bear coarse gold particles. i Monthly …
