why sand under concrete? Fine Homebuilding

Aug 19, 2004 And Why is that a problem? As I am told with the plastic directly under ninth the concrete all the water in a 5 inch slump has to go up and as it moves up and sits on top of the concrete to evaporate you get separation in the concrete because the water sits on top of it to long. The concrete will not get to be the strongest it could be.

Gold CIL & CIP Gold Leaching Process Explained CCD

Jan 02, 2013 CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process.

The process design of gold leaching and carbon-in-pulp

The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as only one set of agitators for both leaching and

Leaching & Adsorption Resource Book

Carbon Adsorption Theory After the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. The method of recovery of gold from the process slurry is by carbon adsorption. Adsorption is a term used to describe the attraction of a mineral compound to the surface of another material.

For mill, agitated-tank leaching operations, gold is extracted directly from the leached pulp in either a carbon-in-leach (CIL), or a carbon-in-pulp (CIP) plant. In both these cases, the coarse granules of activated carbon are mechanically mixed with the
