sample preparation), initial calibration verifiion, continuous calibration verifiion, internal standard (scandium), interference check solution, and spiking standards PROCEDURES Analysis by ICPOES will follow US EPA Method 6010b – Inductively Coupled PlasmaAtomic Emission Spectrometry.
Insitu leaching mining (see the mining background page) has been introduced as the required mining method for those new mines that can physically implement this technology. Saponifiion, a step of the refining process that leaves the wastewater highly toxic, can be improved through a newly discovered method that eliminates the need for ammonia.

An advantage of this method is that the random errors in preparing and reading the standard solutions are averaged over several standards. Moreover, nonlinearity in the calibration curve can be detected and avoided (by diluting into the linear range) or compensated (by using nonlinear curve fitting methods).
