Improved ways to crush and process the ores were developed in Europe during the Industrial revolution, and ore processing ceased to be magic and came into the realm of science. Yet it was only from the push of the great gold rush waves of the new world, which began in the mid 1800s in California, that real progress was made. Sound and efficient methods were developed and costs were reduced until by 1900, hard rock mining was a well developed technology. The standard methods of processing
Ore processing technologies extract economically valuable minerals and metals. They include the collection of naturally occurring metals and minerals (e.g., placer gold or lode silver), crushing and grinding ores, mechanical concentration of ores containing metals and minerals, and breaking down the ores with chemical, heat, and electrical processes. "Free milling" ores require the simplest processing technologies.

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. That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich. Many mines

Ore is processed in a complex minerals processing plant. The open-pit and underground mines supply both course gold and refractory ore to a processing plant that includes crushing, grinding, gravity recovery, flotation, oxidation (autoclave) and Carbon In Pulp (CIP) circuits to produce a gold dore product and a high grade pyrite concentrate for shipment to offsite refineries and smelters for final processing.

This process does not result in gold that is 100% pure, but it does eliminate the bulk of the impurities. The problem with this method is the release of the mercury vapor into the environment. Even if the equipment is used to catch the vapor, some still can get into the atmosphere. Mercury also can get into the soil and water if it still is
