2 days ago· SEMPORNA: Seorang bekas anggota Tentera Laut Diraja Malaysia (TLDM) hilang manakala rakannya selamat selepas bot mereka karam dipukul ombak di perairan Pulau Mabul, dekat sini, pada Sabtu. Dalam kejadian kira-kira jam 7 pagi itu, bot dinaiki Mahmur Ajae, 45, dan rakannya, Salimin Paludin, 44, yang juga bekas anggota TLDM terbalik ketika cuaca buruk.
Zircon composition has great potential as a pathfinder for porphyry Cu ± Mo ± Au systems. The present study used a large integrated laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) U-Pb age and trace element dataset for both infertile and fertile magmatic suites in order to elucidate distinctive zircon signatures diagnostic of metallogenic fertility of the parent magma.
Nov 20, 2015· "Batu Hijau is a porphyry copper deposit containing small amounts of gold and silver..... On average, gold yield is much lower at only 0.37 gram per tonne processed. This means that a lot of work is needed to obtain small amounts of the metal that can be sold.) (sumber: web Newmont Batu Hijau)
Apr 30, 2015· Ore geology and Mineralization: The Batu Hijau porphyry Cu‐Au deposit is a world‐class island arc type porphyry deposit, located on the southwestern portion of Sumbawa Island, Nusa Tenggara Barat Province, Indonesia. This 12 km by 6 km …
Porphyry indicator minerals (PIMS) Geochemical fingerprints of porphyry deposits • PIMS have distinctive trace element compositions • Distinct from local country rocks (e.g., zircon) • Distinctive of particular mineralization styles and/or alteration zones (e.g., magnetite) • Ideally, PIMS should be resistate, so
At Batu Hijau, ore containing copper and gold is crushed to a coarse size at the mine and then transported from the mine via conveyor to a concentrator, where it is finely ground and then treated by successive stages of flotation, resulting in a copper/gold concentrate containing approximately 26% …

Batu Hijau, Sumbawa; Grasberg, West Papua at >3 billion tonnes at 1 ppm Au, is one of the world's largest and richest porphyry deposits of any type; Tujuh Bukit, Java, still under exploration, but likely to be bigger than Batu Hijau; Sungai Mak and Cabang Kiri, Gorontalo, at 292 million tonnes at 0.50 ppm gold and 0.47% copper; Australia
Ore samples from the Batu Hijau deposit average ~1 ppm Ag and the Ag/Au ratio is ~2 (Fig. 15; Newmont Mining Corp., unpub. data). The Ag/Au ratios in quartz veins near Batu Hijau vary from >50 in peripheral base-metal sulfide veins to ~5 closer to the deposit.
