4. Vancouver-based Lundin Gold projects it will produce between 405,000 ounces to 445,000 ounces of gold in 2022 at its Fruta del Norte mine in Ecuador. This is based on an average throughput rate of 4,200 tonnes per day, with a headgrade estimated to average 9.79 g/t of gold. Average mill recovery for 2022 is estimated to be 89%.
Milling Rate = 500 tonnes/day (550 sptd) Crushing Rate = 2 x 12 hour shifts/day 7 days/week x 350 days/year. Head Grade = Au 7 gms/tonne (0.21 Tr.oz/ston) + Ag 260 gms/tonne (7.6 Tr.oz/ston) Metal Recoveries = 95% Au and 75% Ag Gold Process Description
Gold and Silver Leaching. For Gold and Silver, the most common leachants used are Na or K cyanides in the presence of oxygen, Thiourea (NH 2. CS.NH 2), also in the presence of oxygen, or Ammonium polysulphide (NH 4) 2 Sx, especially for Gold. Optimum physical conditions for cyanidation are: Maximum temperature of 85 o C, Operating ph range of 9 ...

Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. The advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually low
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
accordance with standard specifications, various aspects related to least cost feed formulation, raw material quality testing, storage, production etc. need to be taken into consideration. It is essential that, feed milling plants have a qualified and trained animal nutritionist.
