Effects of iron-ore mining and processing on metal ...

2008-8-15  Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, iron-ore mines act as important sources of major metals, mainly Fe and Mn, but also associated trace metals into the environment (Ratha and Venkataraman 1995; Wong 1981; Zabowski et al. 2001).

Sustainable Development and the Australian Minerals

(11) Foreign investment in mining and mineral processing provides for expansion of private investment, development of internationally competitive export-oriented industry and the creation of employment opportunities. However, one aspect of foreign investment relates to the relatively low level of added value processing of minerals in Australia.

Mineral Dust and Iron Solubility: Effects of

There is significant iron deposition in the oceans, approximately 14–16 Tg annually from mineral dust aerosols, but only a small percentage (approx. 3%) of it is soluble and, thus, bioavailable. In this work, we examine the effect of mineralogy, particle size, and surface area on iron solubility in pure mineral phases to simulate atmospheric processing of mineral dust aerosols during transport.

Effects of Pretreatments on the Zeta Potential ...

2012-1-2  The effects of pretreatments on the zeta potential characteristics of hematite were investigated on a number of hematite samples. The bulk of the test work was conducted on a sample of naturally occurring hematite from the Iron Prince deposit in the Middleback Range area of South Australia. The iep of the ROM ore was measured as 2.6, which was only slightly raised by ultrasonic cleaning.
