Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
The open pit at the Lihir Gold Mine Papua New Guinea is planned ultimately to reach more than 200 m below sea level. Cooling and depressurization of the geothermal resource associated with the gold mineralisation is an essential part of the mining operation.
The Lihir Gold Mine Lihir Island is located in Papua New Guineas (PNG) New Ireland Province about 700 km northeast of Port Moresby (Fig. 1) Figure 1 Location of Lihir Gold Mine (Source hir Island is situated off Papua New Guineas New sby. ng There are 7 100 people living in the Lihir group of islands ce g e Mining Technology undated).
Having the third largest gold reserves in the world it has attracted large amounts of investments into mining. Among them is the Lihir mining operation which is one of the two biggest mines in the country . The mine has been operated by Lihir Gold Ltd. and is currently owned by Australian miner Newcrest (see project details).
However gold production fell 2.8% from the same quarter last year due to lower output from its Cadia and Lihir mines. At Lihir Papua New Guinea the

The Lihir gold mine in Papua New Guinea dumps over 5 million tons of toxic waste into the Pacific Ocean each year destroying corals and other ocean life. Companies mining for gold and other metals in total dump at least 180 million tons of toxic waste into rivers lakes and oceans each yearmore than 1.5 times the waste that U.S. cities send to landfills on a yearly basis.
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 has submitted a conditional proposal to the PNG government to develop an open pit mine and to install a process plant and associated infrastructure
Lihir processing plant is designed to process 3.6 Mtpa of ore containing 7.2% 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 sulphur.
