For over 40 years, ALS has been associated with the testing of thousands of ore deposits worldwide, many of which have gone on to be successful industrial operations.

Zambia has built 10 milling plants to process gold in a drive to formalise artisanal and small-scale miners and diversify from copper mining, state mining investment company ZCCM-IH said on Wednesday.

The plant is aimed at chemically processing the gold stockpiles from two old gold mines, and concentrates from the gold milling plants. The vat leaching plant which is scheduled to be completed by June 2020 will have a processing capacity of 8, 000 tonnes of ore material per leach, and a targeted gold production of 17.5 kilograms per month.

A mining company in South Africa used fire assay method to analyse samples from a new mining area. The results obtained were accurate and proved the high gold content of the samples, which made this method …

Some gold ores are refractory ores. They are difficult to process with regular cyanide leaching. This is because sulfide minerals encapsulate the gold particles. To address this, a pre-oxidation step is required. It breaks down sulfide minerals and exposes gold particles to the leaching stage. There are a few pre-oxidation methods:

An Act to revise the law relating to the exploration for, mining and processing of, minerals; provide for safety, health and environmental protection in mining operations; provide for the establishment of the Mining Appeals Tribunal; repeal and replace the Mines and Minerals Development Act, 2008; and provide for matters connected with, or incidental to, the foregoing.

In the context of its processing, gold deposits are typically classified, for the purposes of simplification, as: 1) free milling, and 2) refractory ores (including complex and carbonaceous). Based on their mineralogical characteristics and their mineral processing techniques required to liberate them, however, gold ores can be classified further.

technology of refractory gold deposits [2,3]. The gold mineral should be pretreated before smelting due to the low grade of gold in the ore. The pretreatment process of gold mainly includes gravity separation, flotation, microbial oxidation, etc. [4,5].

Ore sorting in mineral processing is separating the ore according to their size subsequent to the crushing and grinding of ore. For ore sorting in mineral processing, there are several methods. Depending on the mineral being processed, some may require more than one method before being determined ready for the next ore beneficiation process.
