  • Metal Recovery Rate How to Interpreted the Mineral

    Example: When you read a press release in which a mining company announces a resource of 500 million tonnes of 1% copper and a mineral recovery rate of 80% you should actually read that the company announces 500 million tonnes of (1% * 80% =) 0.8% sellable copper.

  • Ore sorting Preceding processing Ausenco.

    Guthrie said the second case sorting of ore to increase grade and reduce subsequent processing and transport costs is generally only economically favourable if the processing and ore transport costs are high (in relation to head grade) and the recovery of values is also high (eg >95%) .

  • What is a theoretical graderecovery curve? An example.

    The theoretical graderecovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process. The theoretical graderecovery can be readily used to quickly identify potential recovery

  • What is the Relationship between Head Grade and Mineral

    Relationship between Head Grade and Mineral Liberation EXAMPLE The red/white dot points to the actual monthly liberation of 42% VS history. The poorly monthly results can be better understood as better results will be obtained at +50% liberation.
