The Lihir deposit has dimensions of about 1,500 x 3,000 m and has about 500 m in depth extent A long section through the Lihir deposit is included The deposit remains open at depth, along strike, and to the east, where it is currently limited by the Pacific Ocean Gold is the only metal of economic significance present within the Luise CalderaThe Lihir deposit in Papua New Guinea (PNG) contains an estimated mineable reserve of 137 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 and to install a process plant and associated infrastructure The lihir gold project; Process plant design Lihir Island gold deposit consists of two orebodies, Minifie and Lienetz, located in the Luise Caldera on the east coast of Lihir Island They will be mined by conventional open pit methods Because of its lower stripping requirement and higher gold content, Minifie orebody will be mined firstLihir Facts MiningAmong them is the Lihir mining operation which is one of the two biggest mines in the country [1] The mine has been operated by Lihir Gold Ltd and is currently owned by Australian miner Newcrest (see project details) The mine is located on Lihir island, Environmental and social concerns at the Lihir gold Lihir processing plant is designed to process 36 Mtpa of ore containing 72% sulphide sulphur at a gold grade of up to 13 g/t and a plant availability of 86% The instantaneous design feed rate is 375 t/h of ore containing 27 t of sulphide sulphurLihir Facts Processing
Extraction of Gold
The extraction of gold by the cyanidemethod is of great technical importance It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically The process was suggested by Mac Arthur and Forrest in 1385, and is based on the wellknown solubility of gold in potassium This was a geometallurgy exercise in which 8 lithologies from the same openpit gold deposit were tested for Silver and Gold Extraction and evaluation of the response for 2 Processing Methods The feed gold and silver was amenable to gravity Gold Processing Methods Gold Ore Extraction The GravityBorax Method GBM is still unknown to most Artisanal and smallscale gold miners (ASGMs) worldwide as most still use mercury to extract gold “Wholeore amalgamation” is a technique that requires the use of 10–25 g of mercury to produce 1 g of goldMethod of Gold Extraction using Borax Small Scale The Lihir deposit in Papua New Guinea (PNG) contains an estimated mineable reserve of 137 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 and to install a process plant and associated infrastructure The lihir gold project; Process plant design Gold Mining Underground and The Extraction of GoldExtraction of Gold by Cyanide LeachingExtraction of Gold by The Amalgam ProcessExtraction of Gold Using The Electrowinning ProcessExtraction of Gold Using The Borax Process Even though the precious metal gold only occurs very rarely indeed, it can be found almost everywhere on the planet in the gold mining in Indonesia method of extracting
