is zinc precipitation. Originally, solutions were passed through boxes containing zinc metal shavings. Gold and silver would precipitate out of solution by a simple replacement reaction procedure. Around 1920, zinc shaving precipitation was replaced by the Merrill-Crowe method of zinc precipitation.

The precipitation process for hydrated precipitates from sulfate solutions was carried out by using both solid and dissolved form as a reagent-precipitant. During the precipitation, the stock solution was heated in order to intensify the process and produce more easily filtered precipitates.
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
