  1. The process design of gold leaching and carbon

    gold plant will be that of the leaching and carbon-in-pulp circuit (CIP) The reagent and Although air agitated leach tanks were commonly used in the industry mechanically agitated reactors are preferred due feed pre-screening the pulp flows through a cascade of well-mixed adsorption tanks

  2. Basics of Leaching

    Simply put leaching generally refers to the removal of a substance from a solid via a liquid extraction media The desired component diffuses into the solvent from its natural solid form Examples of leaching include the removal of sugar from sugar beets with hot water and the removal of nickel salts or gold from their natural solid beds with sulfuric acid solutions

What Can You Use in a Septic System to Unclog the Leaching

Effluent from a septic tank with high sludge levels will carry solid waste that can quickly clog the leach bed No septic treatment dissolves sludge a major cause of clogged drain fields When sludge or floating scum in the tank threatens the tank's efficiency you'll need a professional service to pump out the contents for disposal Tank and vat leaching involves placing ore usually after size reduction and classification into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution In tank leaching the ground classified solids are already mixed with water to form a slurry

Case Studies

A slurry containing 50% by weight ore flows continuously through a series of large tanks to extract the precious metal The slurry is first aerated without cyanide present to minimize the cyanide consumption (pre-aeration) It then flows into the CIL (Carbon-In-Leach) tanks where cyanide oxygen and activated carbon are added Alternative septic system designs are used for new or replacement septic systems on difficult sites where soil conditions (such as a rocky site limited soil percolation rate or high ground water level) or other terrain conditions (such as limited space for a septic system or steeply sloped sites) do not permit the installation of a

Alternative Septic Systems For Difficult Sites

Some larger community systems use pre-treatment of the effluent before it reaches the leach field a mini version of a sewage-treatment plant But most single-home systems rely on bringing in natural or manufactured materials that require less surface area for leaching than The tank tops starting with the third compartment are badly decayed while the walls show little or no decay In 1960 precast tanks became common One manufacturer quickly became the dominant supplier in our county The tanks installed from 1960 through the mid- to late 1970s held up pretty well Tanks installed after that decayed rapidly

Septic System Types

The first component of all septic systems is the tank Most tanks are split into two compartments and have pipe baffles and an outlet filter to ensure the solids stay in the tank The biologic process begins in the tank where the effluent separates into layers and begins the process of decomposition The slurry (1) of ground ore and lime moves into a series of six leach tanks (2) where a sodium cyanide solution is added The tanks provide sufficient retention time to allow the gold and silver to be dissolved by the cyanide solution Oxygen is added to assist in this process The slurry then moves through a series of carbon adsorption tanks (3)
