Reference Tables

This table provides values of atmospheric pressure (in kiloPascal and millimeter of mercury) and air density (in kg/m³) at varying altitude (in meter) and temperature (in °C). The tabulation starts from 0 m to elevation of 6000 m.

This is useful for example in determining what air flowrate should be supplied to a column flotation at located at a certain elevation when specifications are at normal temperature and pressure.

This table provides a handy reference to bulk density of 1,975 different materials. It is useful for designing for example a storage bin for activated carbon.

This table provides an estimate of the temperature in degree centigrade based on color. This is useful on occasion like doing cupellation when a proper temperature gauge is not available.

This table provides the formula, specific gravity with respect to air (sg = 1), known effects on humans, explosive limits, characteristics and place where normally found for some common gases and vapors in mineral processing.

This is useful for example in determining if say nitrogen oxide will 'float or sink' in air or what gases may settle in pits, sumps or depressions in the plant.

This table provides the formula, major component distribution and specific gravity of common minerals.

This table provides the various cyanide-metal compounds and complexes that may be found in gold processing. This is useful as a reference in determining the strength of bonds the metals form with cyanide.

This tables shows the various cyanide compounds that are covered in a particular cyanide detection test. For example, when testing for free cyanide, this will include cyanide as CNˉ, HCN(aq) and HCN(gas).

This table provides the density of common materials in kilogram per cubic meter.

This table provides a diagnostic matrix in determining the effects of changing cyclone feed rate, cyclone feed density, vortex finder diameter, apex/spigot diameter and inlet diameter on cyclone operating pressure, d50c, fines bypass fraction, classification efficiency, cyclone underflow percent solids and cyclone overflow percent solids.

This table provides a diagnostic matrix in determining the variables (water addition, throughput, grinding media addition) to adjust when power consumption and bearing pressure are changing.

This table provides a diagnostic matrix in determining how to adjust underflow pumping rate and flocculant addition rate when bed level, torque or underflow density is changing.

This table provides the composition of air in terms of the various gases, their formula and concentration in mole per mole air, percent by volume, kilogram per kilomole air and percent by weight.

This table lists the metal concentration, reaction, metal valence and equilibrium electrode potential for the reduction of metal cyanide ions. This is useful for example in determining the plating sequence or electro-deposition of metals during electrowinning of gold.

This table provides conversion of hardness scale from Rockwell, Brinell, Vickers, Shore and approximate tensile strength.

This table lists all 118 elements with their atomic number, symbol, name, etymology, group, period, atomic weight, density, melting point, boiling point, specific heat capacity, electro-negativity and abundance in Earth's crust.

This table provides the degree of dissolution of various minerals in cyanide solution. It can be handy in determining if a certain mineral will be a problem when leaching gold.

This table lists the 10 minerals in the Mohs hardness scale with their names, chemical formula, absolute hardness and Vickers hardness.

This table lists the sieve standard sizes in millimeter/micrometer with corresponding equivalent size in inches/mesh, sieve opening in mm and inch, nominal wire diameter in mm and inch and equivalent Tyler.

This tables shows the metric prefixes used by the International System of Units (S.I.) including their symbols and multiplication factors.

This tables shows the solubility of oxygen in water at various altitude, pressure and temperature. This comes handy when determining the oxygen requirement during gold cyanidation.

This table shows the work indexes of some common materials. Values are given in kilowatt hour per short ton and kilowatt hour per metric ton.
