Next, blasting occurs to break down the rock making it easier to move. A fleet of excavators mine designated ore areas and move the gold containing ore to stockpiles. The stockpiles containing the ore will be processed to extract the gold. Trucks move waste to a waste rock stack, which can be rehabilitated to fill previously mined areas.

The effect of pH value on gold extraction for various ore types is shown in Figure 28.4. Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value has no apparent effect. However, the outcome will vary depending on the ...

"Gold is a metal that occurs in a natural state in the crust of the earth. We get minerals from two sources – it's either grown or mined. Mining is the extraction of minerals, and the demand and scarcity of it determines the price for it. Gold is four times heavier than iron, and that is a property that is used in the extraction of gold.
