Gold processing

Gold processing - Gold processing - Mining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied Oxide ore deposits are frequently of such low grade (e g 3 to 10 parts per million) that extensive mineral processing cannot economically be justified In this case they are merely shattered by explosives and then piled into heaps for

Gold processing 101

Gold processing 101 (SAG) mill and ball mill The latter is preferred for wet sticky ores to minimise transfer point chute blockages and can offer savings in both capital costs and long-term operating and maintenance costs However the SAG route is more power-intensive and for very hard ores comes with some process risk in predicting performance More recently a hybrid solution has

Slag

Slag is the glass-like by-product left over after a desired metal has been separated (i e smelted) from its raw ore Slag is usually a mixture of metal oxides and silicon dioxide However slags can contain metal sulfides and elemental metals While slags are generally used to remove waste in metal smelting they can also serve other purposes such as assisting in the temperature control of

Refractory Gold Technology

The process converts the iron arsenic and sulphur to environmentally stable hematite ferric arsenate and gypsum respectively Sherritt's gold process has several advantages over traditional roasting practice The process has low sensitivity to the sulphur antimony and lead content of the feed material allowing increased gold recovery in the mill flotation circuits and/or the direct

Newmont's Nevada

The refractory mill grades are reliant on the level and grade of tonnes produced underground with the surface refractory ore tonnes processed dependent on how much mill capacity is not used by underground ore The full range of processing equipment used at the key Newmont Nevada operations is listed in the attached tables As stated Carlin has two main processing operations Mill 6 and Mill

Failure analysis of bullnose refractory in reheating

The approach adopted to analyse the root cause for the failure of bullnose refractory was the rigorous analysis of the failed refractory which was collected during the major shutdown of the reheating furnace of Hot Strip Mill at Tata Steel Many big pieces of failed refractory were collected from the furnace but as all were same in appearance focus was laid on the testing of the largest and

Pyrometallurgical Recovery of Gold From Refractory Gold

The problem concerning effective processing of gold ledge ores extremely refractory to loosening has been considered [1] Among gold ledge ores in Central Kazakhstan ores from the Sayak-4 gold-arsenic-cobalt deposit discovered in 1950s have not been processed until the present as they are extremely refractory to loosening and beneficiation [2 3] This papers is devoted to experimental
