Step five: The dropping (sedimentation) of gold from the other metals happens in this step.And this step is completed by treating the solution with a reducing agent such as SO2, sodium metabisulfite, or other reactants. If you are using either SO2 or sodium metabisulfite (SMBS), the gold will not be reduced until the excess or all nitric has been eliminated.

Fracking, in natural gas and petroleum production, injection of a fluid at high pressure into an underground rock formation in order to open fissures and allow trapped gas or crude oil to flow through a pipe to a wellhead at the surface. Fracking has raised concerns over its economic and environmental consequences.

Hydraulic fracturing, commonly known as fracking, is the process of injecting water, sand, and/or chemicals into a well to break up underground bedrock to free up oil or gas reserves. The USGS monitors the environmental impact of this practice across the country, from potential earthquakes to degraded groundwater quality.

Fluid catalytic cracking is one of the most important conversion processes in a petroleum refinery. The process incorporates most phases of chemical engineering fundamentals, such as fluidization, kinetic, mass/heat transfer as well as distillation. The heart of the process is the reactor-regenerator section, where most of the innovations …

Large steam shovels strip the topsoil and excavate the tar sandpits, which are then separated into tar, sand, and water by hot water in an extraction plant. A refinery process called cracking produces a type of oil called synthetic crude oil from the tar. Two tons of tar sands yield one barrel of synthetic crude oil.

Refining output is larger than input. The total volume of products that refineries produce (output) is greater than the volume of crude oil that refineries process (input) because most of the products they make have a lower density than the crude oil they process. This increase in volume is called processing gain. The average processing …
