Gold extraction Wikipedia

The solubility of gold in a water and cyanide solution was discovered in 1783 by Carl Wilhelm Scheele, but it was not until the late 19th century, that an industrial process was developed.The expansion of gold mining in the Rand of South Africa began to slow down in the 1880s, as the new deposits being found tended to be pyritic ore.The gold

» Dry-washing for Gold

A motorized dry-washing machine is excellent for the production demands of a one or two-person operation. Under ideal conditions, it is able to process up to about a ton of raw material per hour, which is the equivalent of what a medium-sized wet sluicing operation can produce.

How to Identify Raw Gold Sciencing

Mar 13, 2018 Fool's gold can be mistaken for placer gold gold found as rounded or flat nuggets in dry and wet stream beds, and rivers or creeks because they both look golden. But real gold stays bright even when out of direct sunlight, and though soft, does not fall apart when you touch it like fool's gold

Reynolds number scaling of the turbulent boundary layer on

The turbulent boundary layer is a critical aspect of most engineering applications involving fluid flow or heat transfer. Unfortunately, many engineering applications involve complex boundary layers at high Reynolds numbers, and cannot be accurately calculated. Since most experiments are done at low Reynolds number, an understanding of Reynolds number scaling is fundamentally important for

Effective Reynolds Number for a swept wing Physics Forums

Jan 22, 2018 Effective Reynolds Number for a swept wing. Suppose we have an infinite straight wing, using a given airfoil. Also, suppose for simplicity the B.L. is completely turbulent, and M<<1 (incompressible fluid). As we know, the forces per unit length are: L=q⋅c⋅c l, D=q⋅c⋅c d, where c l and c d are the coefficients of the 2D airfoil for the

Vertical axis wind turbine Wikipedia

A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes
