Papua mining industry
Crystalline calcite from glistening limestone caves was first quarried as many as 1,500–2,000 years ago. The doughnut-shaped finished carved products would be transported by canoe some 400 km (250 mi) to Yap (now part of the Federated States of Micronesia), and used as currency.
The Koror state government engages in commercial production of dredged coral from the Palau lagoon, with a production capacity of 800 cu m per day. Other states are also involved in coral dredging. A private company supplies aggregates for concrete from crushed basalt rock and beach sand.
Papua New Guinea Gold Mine Project Brief Introduction
The Lihir gold mine is on the island of Lihir, in Papua New Guinea’s (PNG) New Ireland Province, about 700km north east of Port Moresby. The gold deposit is mined using conventional open-pit mining methods. The milling process includes gold ore crushing, grinding, pyrite flotation and re-grinding of flotation concentrate.
In the gold ore crushing process, NFLG offered gold ore crushers and screening equipment. PE series jaw crushers are used in the primary gold crushing stage and CS series CS cone crushers are adopted as secondary gold crushing equipment. Crushed gold are screened into different products through our vibrating screen . In the gold grinding process, you can choose our ball mills which are of higher efficiency and lower cost.
350-400TPH Crushing Production line
You may be interested in our gold ore crushing plant with capacity between 350 tph and 400 tph. This is a medium scale crushing plant which just uses two-stages crushing. If you need much larger scale gold ore crushing plant, our engineers will design it for you. Click to view more detail info about our medium scale crushing plant.
Although this is kind of large scale crushing plant, the biggest point of this plant is that it has used multi-crushing and multi-screening. With PE jaw crusher whose model is PE-900*1200 and two-stages cone crusher both for coarse crushing and for fine crushing, this plant works to produce high-precision particles from big hard rocks. By adopting two-stages screening equipment, it can firstly get one kind of products with required fineness and the left materials can be sent for next screening which can greatly improves the whole plant’s efficiency and precision.
