Sep 28, 2020 Placer Mining vs. Lode Mining. Lode mining, also known as hard rock mining, is the process of extracting gold from traditional veins of ore that are embedded within rocks and other minerals. To extract gold from lode deposits, miners usually blast, mill, or otherwise erode the rock to get at the gold inside.

The gold milling process consisted of three general steps (1) Sorting the ore by size. (2) Crushing the rock. (3) Extracting the gold. The rock fragments were sorted according to size in a grizzly, which was device consisting of a series of spaced bars, rails, or pipes, above a forward moving conveyer belt to a crusher machine.

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.

Sep 12, 2018 Placer gold is a term that refers to gold found in a secondary deposit. Usually gold occurs in lode deposits. However, the weathering of the hard rock and action of rivers and even glaciers in some places have carried the fine gold nuggets and particles and deposited them somewhere else away from the original lode deposit.

Mar 29, 2020 Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
