  • What is Gold Ore worth? High Grade Mining Ore

    Ore is defined as "a naturally occurring mineral containing a valuable constituent (as metal) for which it is mined and worked". In other word, ore is the most basic raw form of a mineral, which requires additional processing for the valuable minerals (gold) to be removed. A single piece of gold ore generally has very little actual gold content.

    Refractory ores are defined as those which yield low gold recoveries, requiring complex and costly chemical pre-treatment prior to cyanidation. Refractoriness is directly controlled by ore mineralogy, generally resulting from the presence of either naturally occurring ''preg-robbing'' carbonaceous minerals or submicroscopic gold.
