World mineral loss and possibility to increase ore recovery

The total mineral loss in mining and mineral processing is on average 37.2% of the actual production (metal content or final mine product) as the ore recovery ratio is 81% in mining and 90% in mineral processing. This corresponds to a vast amount of mineral loss for the world every year.If the solution is rich enough can be treated by zinc powder and the precipitated obtained (cement) obtained will be sent to retorting and smelting. For gold extraction the strength of cyanide solution ranges from 0.01 to 0.05%. Lime is added to the process in order to have a pH near to 10-11.Gold Extraction & Recovery Processes 911 Metallurgist

Lime use in gold processing A review ScienceDirect

If gold liberation can be achieved, the presence of pyrite has a limited impact on cyanidation gold recovery (Deschênes et al., 2002), because of the minimal direct reaction of pyrite with cyanide to produce thiocyanate, SCN −, Reaction (13), (Kianinia et al., 2018). (13) 4 F e S 2 + 8 N a C N + 3 O 2 + 6 H 2 O → 8 N a S C N + 4 F e OH 3Pressure oxidation is a widely accepted method to treat refractory gold ores. Gold recovery is generally lower from alkaline than acidic pressure oxidation discharge due to passivation and incomplete oxidation of mineral. Gold ore from Goldstrike, NV, is a typical refractory gold ore containing sulfide and carbonaceous matter. Alkaline pressure Enhanced Gold Recovery from Alkaline Pressure Oxidized

Hydrometallurgical Recovery of Gold from Mining Wastes

Gold is a highly required material for a wide range of personal and industrial applications. The high demand for gold, together with the shortage of natural resources and high pollution potential of wastes generated during mining and ore processing activities led to search for alternative sources of gold. A possible source is represented Gold recovery methods. Following leaching, gold ions remain dissolved in the solution, together with other elements. It is necessary to recover gold ions from this solution, separating them from the other dissolved metals present. This section of the paper reviews some of the most common methods used to recover gold from leaching solution. A systematic review of sustainable gold extraction from raw

A 20Mt/a mill will have a capital cost within $10,000 /t/h and $20,000 /t/h (Lane, Fleay, Reynolds, & La Brooy, 2002). Typical operating costs for mills used in gold extraction are summarized in Table 3. The selection of a mill size is ultimately a function of the economics of the project and which mill size will maximize the project NPV.
