Mar 01, 2012· The process is time-consuming and occurs through repeated steps of separation. The yield of gold is difficult to ascertain prior to the extraction process. An experimental company, GoldLake, Inc., has mastered the process of gravimetry; they no longer use any chemical processing agents and use water instead (Carter, 2010). Mining waste is

Determination of Silver by Fire Assay Gravimetry Combined

The fire assay gravimetry is an old and classical method. It is one of most commonly used and most effective methods for the separation and analysis of precious metals due to strong representativeness, high accuracy and good stability. However, the fire assay gravimetry also has some disadvantages such as long analytical procedure and systemic lower analytical results (especially for silver).

Gravimetric Analysis Steps and Definition

Gravimetric analysis is a type of lab technique used to determine the mass or concentration of a substance by measuring a change in mass. The chemical we are trying to quantify is also known as the analyte. Read more about the Classifications and advantages and disadvantages of
