  • What is heap?

    The process manages its allocated heap by requesting a chunk of the heap (called a heap block) when needed, returning the blocks when no longer needed, and doing occasional garbage collecting, which makes blocks available that are no longer being used and also reorganizes the available space in the heap so that it isn't being wasted in

  • Gold extraction

    Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver (as electrum), or sometimes with mercury (as an amalgam). Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as

  • 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
