The lihir gold project; Process plant design ScienceDirect

The Lihir deposit in Papua New Guinea (PNG) contains an estimated mineable reserve of 13.7 million ounces of gold in refractory sulphide ore. RTZ, through its subsidiary Kennecott Corporation and in joint venture with Niugini Mining Limited, has submitted a conditional proposal to the PNG government to develop an open pit mine Gravity separation has been utilized in gold plants as the primary recovery mechanism or alternatively ahead of other downstream processes such as flotation and cyanidation since the inception of mineral processing.

1. Grinding and size classification to reduce the ore down to a fine particle size. 2. Leaching and adsorption to extract the precious metals from the rock. 3. Recovery of gold to produce dore bullion bars. Fig. 1 shows the gold plant under investigation. The plant is divided into 4 main areas: (1) crushing, (2) grindingFor modern large gold plants, the most typical flowsheets are crushing circuits (for heap leaching), autogenous/semiautogenous (AG/SAG) ball-mill circuits, or HPGR-ball-mill circuits. Such flowsheets dominate the 20 largest gold producers in Table 17.1. Examination of the flowsheets within each category, though, also demonstrates that Comminution Circuits for Gold Ore Processing ScienceDirect

This flowsheet is the lowest in price, and can be used on what are commonly termed as “free milling” gold ores where a high percentage of the values are free and where these values are unlocked at reasonably coarse grinding. This flowsheet is often used for Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and.

The encapsulation impedes access of cyanide to gold for dissolution, reducing the effectiveness of subsequent CIL circuits in copper–gold plants. A common pre-treatment method to overcome this type of refractory ores is to increase gold liberation by ultra-fine grinding of iron sulphide minerals [5], [6], [7].Despite the differences in scale between the 450 mm test and the 1.8 m pilot plant tests (along with differing circuit closing sizes, and varying pilot-plant operating conditions), the similarity in distributions of unit power requirements reinforces the concept that SAG throughput is defined by a specific unit power requirement.. 3.
