The conditions of declining gold grade in the ore, increasing depth of excavation, and de-creasing unallocated stock of deposits make it necessary to develop efficient solutions for the mine-to-mill process, which have to be …

Profit margins are being squeezed by rising costs and decreasing commodity prices, while labour productivity is greatly affected by intermittent labour unrest. This paper analyses how the South African gold mining industry has performed pre-, during, and post the global financial crisis of …

The role of innovation and technologies in the mining sector's efficiency and productivity has received empirical attention, with some analyses showing that innovation has offset the decline in ore grades (Rodríguez et al., 2021; Villena and Greve, 2018).

Our findings demonstrate how new ASGM technologies in Kamituga have the economic advantage of allowing the processing of considerable quantities of ore (gold hosted by quartz veins) far more rapidly than had been the case previously.

reduce mercury use, and improve gold recovery using appropriate technology. During a field visit in November 2019, samples of gold ore, crushed and milled ore, concentrates, and tailings were collected from ASGM operations. On average hard rock gold is finer than 100 microns. This makes the use of a sluice box inefficient with expected recov-

Based on a case study of ASGM mechanisation in the major mining town of Kamituga, we investigate the economic impact of this process on the productivity of ASGM and the profitability of its...

Test work on bulk low-grade gold ore stockpile samples from Central Norseman Gold Proprietary Limited has been conducted, indicating high gold recoveries as well as high material rejection rates. A financial model, based on these results, evaluates grade sensitivity and identifies a minimum stockpile grade for adequate financial returns.
