Shine Iron Ore Project, Perth, Western Australia, Australia

While the early site construction works were commenced in January 2021, the mine is expected to produce its first ore in April 2021. The Shine iron ore project is expected to produce approximately 2.8 million wet metric tonnes (Mwmt) of iron ore over a mining period of two years, in stage one. Location, geology and mineralisation

Synthesis of a Goethite Pigment by Selective Precipitation of …

Conventional treatment of acid rock drainage (ARD) from coal mines generates large volumes of sludge, which requires further treatment and disposal. The aim of this work was to study the recovery of iron by selective precipitation to synthetize goethite for use as pigment. Goethite particles were successfully produced, and presented a particle …

Goethite

Goethite is an iron oxide mineral. Although iron ores were found at several locations in Cornwall, iron was never a significant product, contributing less than 1% of the UK's total output, even during the most productive years of the 1850s–1870s. Restormel mine was one of Cornwall's most productive iron mines.

Restormel Royal Iron Mine, Lostwithiel, Cornwall, England, UK

8.1 x 6.2 x 5.4 cm. This old iron mine (closed in 1883) is famous for fine crystallized goethite specimens and this is a showy and excellent example accented with sparkly drusy quartz. Radial clusters of lustrous, striated, gray-black prisms to about 1.5 cm are densely and attractively clustered atop the goethite and hematite matrix. This is a ...

9 Ore Deposits and Economic Minerals – Mineralogy

Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of …

Rust to riches: goethite's role in shaping Australia

How is goethite formed? Goethite forms when iron-rich minerals weather and become oxidised. It is the main component of rust, and gives colour to many Australian soils, rocks and landscapes. The formation of goethite in Australia is closely tied to our unique geological history. About 2.6 billion years ago, Earth's atmosphere lacked oxygen.
