its comparatively high gold recovery has made amalgam an integral part of the small scale gold mining operations. In PNG, most of the gold deposits worked by small scale miners are alluvial deposits, in which the gold particles are liberated from the gangue particles. It is customary to use riffled sluiceboxes

Artisanal and SmallScale Gold Mining Without Mercury
the Requirements for a clean technology in small scale gold mining (1) the technology must be technically efficient (more than the traditional methods) Technicaleconomical criteria: the equipment, if possible, needs to be manufactured locally long life span simple and safe handling and maintenance (also by less qualified personnel)
Methods . Gold capture, as well as the amount of mercury released into the environment, was analyzed for two amalgamation methods and the borax method. The Amalgamation Methods . Mercury is used in gold mining because of its ability to bind to gold to form an alloy which helps separate the precious metal from rock, sand and other material.
Artisanal and SmallScale Mining (ASM): ASM is a collective term embracing both small scale and artisanal mining. It covers formal or informal mining which is characterised by low capital intensity and high labour intensity and relatively simple methods for exploration, extraction and processing.
The Artisanal and Smallscale Gold Mining (ASGM) sector in Nigeria is in a deplorable state characterised by the use of inadequate mining and processing methods and manual tools by the local
For extracting gold from lowgrade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide as laid out in the International Cyanide Code. Gold refining

The expanded EQV formula for income in gold mining is shortly: INCOME = Gold Production (Expenses(EQV) + Expenses(Other)) The INCOME equals the GOLD PRODUCTION less the EQV EXPENSES and OTHER expenses. Small scale mining groups and associations usually do not invest much or pay more money than they produce. This is very important in life and in business. One has to
