— The EXAMPLE Gold Mill is designed to process 500 tonnes per day of ore. The flowsheets are conventional and consist of two stages of crushing, single stage ball mill grinding, cyanidation and a Merrill-Crowe precipitation circuit for gold and silver recovery.

 — The approximate running costs for crushing plants of different capacities up to 4,000 tons per day on the basis of an eight-hour crushing day are easy to calculate. The figures must be regarded only as a rough guide to the average costs of modern installations ; they are direct costs and include no overhead charges.

Mining is a major cost, and this can vary from only a few pence per ton of ore to well over £50 t −1. High-tonnage operations are cheaper in terms of operating costs but have higher initial capital costs.

 — Approximately 1300 tons per day of arsenical gold is treated for an overall cost of $1.05 per ton, distributed as shown in Table 98. The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99.

Modular Gold Plants (MGP) by Resources Gold Technology are complete turnkey modular gold plants designed for the 200 to 600 ton per day producer.

 — Generally, milling costs range from $3 to $10 per ton of ore. The cost of milling gold ore depends on several factors, such as the amount and type of ore being processed, the size of the...

Energy costs are calculated at 250 MWH/ton of silver-equivalent and 20 GWH/ton of gold-equivalent, whereas most other materials in our research are in a range of 0.7 – 70 MWH/ton. Likewise, CO2 intensity is very high, at 100-150 tons/ton of silver-equivalents and 9,000 tons/ton of gold-equivalents.

 — What is the Cost of Mining Gold? We've analyzed the Top 50 Gold Mines to find the cost per ounce of gold by continent. The top 50 gold mines alone contain more than 33.5% of the world's gold ounces.

Accurate capital costs are estimated from the lengths, sizes, and unit costs of planned mine development; manufacturers' quotations for specific equipment; quantities and contractors' unit costs for excavation, concrete foundations, and installations of piping, electric services, and equipment.

 — Although global gold mining output was higher than ever before at 170 tonnes in H1 2023, the production costs per ounce of gold were also at an absolute record level.
