The tailings pond at the Volcanogenic Massive Sulphide copper-zinc-silver-gold Myra Falls Mine on Vancouver Island is shown on Figure 8.2.3. The tailings are contained by an embankment. Also visible in the foreground of Figure 8.2.3 is a pile of waste rock, which is non-ore rock that was mined in order to access the ore.
Open-pit mining, on the other hand, involves removing the topsoil and rock layers to access the ore deposit near the surface. Once the gold ore is extracted, it undergoes further processing to separate the valuable gold from the impurities. This typically involves crushing the ore into smaller fragments and then grinding it into a fine powder.
The highest gold recovery reaching up to 90 % can be achieved in typical oxide gold ore over 90 days leach cycle whereas sulphide gold ores will yield an average of 60 % over the same period.

1. Introduction. Water is a key factor in the planning, design, operation, and closure cycle of any mine site or gold-processing facility. This chapter provides an overview of the commonly used water-management practices for gold-processing sites, including considerations for the site as a whole, and the factors that may need to be considered for …
Unlike hardrock mining, which extracts veins of precious minerals from solid rock, placer mining is the practice of separating heavily eroded minerals like gold from sand or gravel. The word placer is thought to have come from Catalan and Spanish, meaning a shoal or sand bar. The word entered the American vocabulary during the …

Schematic diagram showing principle of jaw crusher showing the path of lumpy feed ore to fragmented product crushed under high pressure of fixed and moving jaws. The type of jaw crusher depends on input feed and output product size, rock/ore strength, volume of operation, cost, and other related parameters.
Two tests were made in the laboratory of which I have a note: one for 10 minutes and one for 15 minutes. The ore contained $6.50 gold and 2% copper; 12% of this sample would remain on a 60-mesh screen. The first one gave a concentrate containing $22.70, 9.4% copper, and 18% insoluble, with an extraction of 51% of the gold and …
Refractory Gold Processes. Gold can be leached and extracted/recovered in several ways. Even if you gold is "refractory" in pyrite or arsenopyrite, you can still get much value from your ore/rock depending on the economics of capital and operating cost. The cheapest and fastest option is to simply grind and CIL the whole thing according the ...
The enrichment techniques for gold are controlled by the ore mineralogy, thus textural and mineralogical studies can assist and improve the mineral processing of these ores (Zhou and Cabri 2004 ...
Treating ore by milling is generally a two-step process, first the ore must be crushed, then the crushed ore must be treated to separate the valuable mineral content from the waste rock. Elaborate milling operations at Tomboy, Colorado. The earliest, and simplest method of crushing ore was the use of arrastras.
Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold. To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods. Gold nuggets, a popular form of Gold with collectors, are formed when erosion causes a large piece of Gold to separate from its ...
Flotation of Gold Ores 17.1 INTRODUCTION The recovery of gold from gold-bearing ores depends largely on the nature of the deposit, the mineralogy of the ore and the …
Gold-containing ore processing technology has been developed by using chemical, X-ray phase, mineralogical, X-ray fluorescence analyses. The results of experiments on the gold recovery from a concentrate with a particle size of 10 and 4 µm are presented, including options for direct cyanidation without preliminary oxygen oxidation, …
The scraper is a kind of circulating earth-moving machine. The scraper can be integrated to complete shovel, load, transport, and rock and soil discharge four operations. The scraper is mainly used for medium – distance large-scale ore mining operations. There are two basic types of scraper for mining ore: crawler scraper and …

The low unit costs remain essential for the Macraes Operation as the ratio between the amount of ore dug to the amount of waste rock dug is 1:10 (also known as the stripping ratio). So, to put this in perspective, to obtain one to two grams of gold the open pit mining operation must move 11 tonnes of rock. Underground Mining

The Mining Process. 1. Mining – Open Pit and Underground — To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
Spain plundered, then mined, large amounts of gold, both alluvial and from hard-rock deposits, in the old Aztec and Inca empires in the first half of the 16th century, and Portugal followed up with discoveries in its African and Brazilian colonies. Russia mined gold in the Urals, and then Siberia was opened up for its alluvial gold deposits.
He finds gold in rocks apparently free from sulphides. J. E. Spurr traces the origin of certain quartz veins direct from igneous magmas by a process of magmatic segregation, and derives an auriferous quartz vein from an igneous siliceous dyke. The magmatic concentration is succeeded by aqueous concentration acting underground by …
