Mining pools help make revenue for miners more predictable. Huge drops in weekly numbers could highlight that some mining pools are either being turned off or they have decided to mine other currencies. If a mining pool were to control more than half of the total hashrate, it could (while unlikely) lead to a 51% attack on the network.

The actual mining of diamonds as an industry can be traced back to India to around 800 to 600 B.C. India was the only known source of the rocks for over a thousand years, until they were unearthed in Borneo around A.D. 600. During the Middle Ages, the diamond was overshadowed by some of the more colorful gems like the ruby and emerald.

Our process model does not attempt to capture all of these possible routes through the data mining process because this would require an overly complex process model. The fourth level, the process instance, is a record of the actions, decisions, and results of an actual data mining engagement. A process instance is

The ability to extract copper from ore bodies was well-developed by 3000 BCE and critical to the growing use of copper and copper alloys. Lake Van, in present-day Armenia, was the most likely source of copper ore for Mesopotamian metalsmiths, who used the metal to produce pots, trays, saucers, and drinking vessels.

The mining process can be broken down into two categories: Surface Mining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface. Underground mining. The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges ...

A Process Flow Diagram (PFD) is a type of flowchart that illustrates the relationships between major components at an industrial plant. It's most often used in chemical engineering and process engineering, though its concepts are sometimes applied to other processes as well.
