  Spike-and-recovery and linearity-of-dilution assessment

  2024522 · Linearity of dilution refers to the predictability of spike or natural sample recovery for known dilution factors in the desired assay range. The two kinds of information are related, and experiments can be designed to test both spike recovery and dilutional linearity simultaneously. The following discussion considers each one separately.

  Ore Dilution Rate, Classification and Calculation of

  202364 · Classification Ore dilution is divided into mining dilution and ore drawing dilution. Mining dilution, also known as primary dilution, means that in the mining process, due to the influence of comprehensive factors such as the mixing of surrounding rock in the hanging wall and footwall of the ore body or stone, the grade of the mined ore is lower …
