How Your Septic System Works | US EPA

The septic tank digests organic matter and separates floatable matter (e.g., oils and grease) and solids from the wastewater. Soil-based systems discharge the liquid (known as effluent) from the septic tank into a series of perforated pipes buried in a leach field, chambers, or other special units designed to slowly release the effluent into ...

Gold and Silver Leaching by Cyanidation

The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890. From there it spread to Australia, Mexico and the ...

Leaching Chamber | On-Site Sewage Facilities (OSSF)

Leaching Chamber. Leaching chamber systems handle wastewater in a similar manner as conventional gravel-filled drainfield systems. The main difference is in how the trench is constructed. A leaching chamber system includes: • A treatment device, generally a septic tank, but it can be an advanced pretreatment component.

Leaching Equipment - Solids Concentration - Beyond Discovery

Impeller-agitated tanks. These can be operated as continuous leaching tanks, singly or in a series. If the solids feed is a mixture of particles of different settling velocities and if it is desirable that all particles reside in the leaching tank the same lengths of time, design of a continuous stirred leach tank is difficult and uncertain.

Leaching and adsorption circuits – for better metal extraction

The sizing of the tanks is calculated based on the time required to completely leach the ore, usually 24-72 hours. The tanks are configured in stages and can be configured in cascade orientation making use of gravity slurry flow or in an active carousel configuration where the slurry is effectively pump from tank to tank.

Leaching in Metallurgy and Metal Recovery

1) Vat Leaching: Also known as "agitated tank" leaching, the lixiviant comes into contact with the metal material in large vats or tanks, which can be stirred, enhancing the reaction kinetics. The metal containing solid, such as concentrate, ore, residue, or slag, often undergoes size reduction via crushing and grinding prior to leaching.

Cyanide Use in Gold Mining - Earthworks

Vat (or tank) leaching: The ore is mixed with cyanide solution in large tanks. Although the chances of spills are lower because the leaching process is more controlled, the resulting waste, known as tailings, is stored behind large dams (tailings impoundments) which can and do fail catastrophically.
