2009-8-27 · mixed adsorption tanks, typically 6 to 8 in number. Conventional practice is to have a mean pulp residence time of about an hour in each tank. The tanks are normally mechanically agitated and each will contain a batch of carbon of concentration 10–25 grams of carbon per litre of pulp (0.5 to 1.2% by volume carbon). The carbon is retained in each

Design copper agitated leach tanks?

2021-9-12 · Designing a leach circuit should consider both ore-specific factors as well as factors involving the interaction between the ore and process equipment. Achieving the optimum leach performance involves combining operating parameters, such as grind size, residence time, chemical conditions (reagent addition levels, temperature, etc.), most of ...

Gold ore Carbon-In-Leaching (CIL) processing technology ...

2018-11-12 · The leach circuit comprises eight stainless steel tanks in series, located outdoors. Each tank is equipped with an agitator. The first tank is a pure leach tank and the following seven are CIL tanks. The flotation tailings slurry is pumped to the fist tank via a trash screen. Sodium cyanide, slaked lime slurry and air are added into the tanks.

Cleaning/leaching a plating tank

2021-1-11 · Normally I would leach the tanks with 1-2% sulfuric acid, and try to get some heat to it, 140 °F if/when possible. What are some options used in the industry? I thought about 35% hydrogen peroxide @ 1-2 mls/litre to add to the sulfuric. After leaching, ph adjust to 6-9 in the tank, then send the waste water to waste treatment. Regards, Eric Bogner

Leaching Plant Design

2016-5-24 · Where wood tanks are not applicable, steel tanks, lined with rubber, neoprene or certain fibreglass impregnated resins are used. Acid-proof brick linings are also used particularly in cases where extreme temperature and abrasion are involved. In cases where toxic fumes are liberated in the leach operation tank …

High Pressure Acid Leach

High Pressure Acid Leach (HPAL) is a process used to extract nickel and cobalt from laterite ore bodies. The HPAL process utilizes elevated temperatures (roughly 255 degrees Celsius), elevated pressures (roughly 50 bar or 725 psi), and sulfuric acid to separate nickel and cobalt from the laterite ore. HPAL has been used since 1961 when it was ...
