Oil wells have positive and negative effects. Their impact on the environment is largely negative. To drill for oil, land needs to be cleared. Drilling also creates waste and adds pollutants to the environment. The oil industry is a big part of the U.S. economy, though, adding millions of jobs.

The gold must be in a fine particulate form (from the grinding circuit). The feed slurry must have an 80% passing size of 75um to achieve suitable gold recovery (refer to cyclone and grinding modules). If the particles are too large they may not be totally leached during their residence time in the tanks and hence will report to tailings.

Vapor lock is a problem caused by liquid fuel changing state to gas while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.Restarting the engine from this state may be difficult.
