However, it may release significant quantities of gold and sulfur.The ultramafic host rocks of the nickel sulfide ores have very low Pd/Ir ratios relative to the nickel ores and also to "normal" ultramafic rocks that are not known to be associated with major amounts of nickel sulfides. This relation may be a valuable exploration guide.

At level 99 Mining, there is a 29% chance to mine an ore from a gold rock each mining cycle (3 ticks or 1.8 seconds), and the dragon pickaxe has a 12.5% chance to be 2 ticks. Assuming maximum efficiency, a dragon pickaxe, and banking at the Crafting Guild this translates to a maximum of approximately 590 gold ore per hour.

How to Recognize Hard Rock Gold Ores. September 2017 by Chris Ralph. I regularly get inquiries along the line of: "Hey, I found this rock, and I think it might be gold ore. How can I tell?" Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.

Nevertheless, gold accounts for a few parts per billion of the mass of the Earth's crust. While it's not economically feasible to extract much gold, there are about 1 million tons of gold in the top kilometer of the Earth's surface. The abundance of gold in the mantle and core is unknown, but it greatly exceeds the amount in the crust.

Rock Densities . Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.

Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.

A rock is either crushed or ground, sodium cyanide (in a ppm level) is added to this rock, and gold reacts with the rock and is leached in the solution. A solution containing gold is reacted with activated carbon, activated carbon gets stripped to produce an enriched solution, and gold is plated in an electrowinning cell.

To test if a rock has gold, rubbing the rock and smelling it can be informative. Gold doesn't have a smell, but pyrite, often confused with gold, smells like rotten eggs due to its sulfur content. This method is easy and doesn't damage the rock, but it won't differentiate gold from mica, which also doesn't have an odor.
