Common Basic Formulas for Mineral Processing Calculations

Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

1. Introduction

Sulfuric Acid (H 2 SO 4) is the most common chemical reagent that is used for the leaching of oxide minerals including copper ones [5]. Among the most important factors of leaching are reagent type, temperature, time and pulp density [12] [13]. The principle of cementation is based on electrochemical differences between ions capacity.
