The Influence of Soil Reconstruction Methods on Mineral Sands Mine Soil Properties
Significant deposits of heavy mineral sands (primarily ilmenite and zircon) are located in Virginia in Dinwiddie, Sussex and Greensville counties. Most deposits are located under prime farmland, and thus require intensive reclamation when mined. The objective of this study was to determine the …

Developing proxies for routine measurement of ore hardness: A mineral sands case study
… for each ore based on its geological and mineralogical characteristics. This study aims to develop geometallurgical proxies to predict the hardness of the cemented hard layers (CHLs) found in a local mineral sands deposit. To achieve this, 43 samples were collected from 11 locations across …

Analysis of Reconstructed Mine Soils on Reclaimed Coal and Mineral Sands Mined Lands in Virginia
… and classified coal mine soils in SW VA and mineral sands mine soils in SE VA to aid development of appropriate post-mining land use interpretations. For coal mine soils, long-term pedogenesis was assessed in sandstone (SS) and/or siltstone (SiS) spoils with and without surface amendments. …

Chemistry and Transport of Metals from Entrenched Biosolids at a Reclaimed Mineral Sands Mining Site in Dinwiddie County, Virginia
… Mg ha-1) biosolids were placed in trenches at a mineral sands mine reclamation site in Dinwiddie County, Virginia in June and July 2006. Vertical and lateral transport of heavy metals from the biosolids seams were determined by analyzing leachate collected in zero tension lysimeters below the …

Sand mining challenges in the Western Cape: The case of the Tormin Mineral Sands and Maccsand Mining and Quarrying Mines
… far less endowed with economically mineable minerals and metal deposits compared to other provinces, mining is even more problematic. This study addressed, in a comparative way, the polemics associated with two mining operations in the Western Cape, revisiting their environmental and …

Elutriation Technology in Heavy Mineral Separations
… separators have been used in several different mineral processing fields for many years. Recent improvements in designs have led to the development of the CrossFlow separator. This new design employs a tangential feed system that has shown promise in several applications. This paper investigates …

Mineral Chemistry of Heavy Minerals in the Old Hickory Deposit, Sussex and Dinwiddie Counties, Virginia
… largest of a series of Pliocene (?) age heavy mineral sand deposits in Virginia and North Carolina. The high density of heavy minerals allows for selective concentration during transport and deposition. Under the right conditions, placers of considerable size can be formed. The elliptically …

Mineralogic and Geochemical Variations within the Old Hickory Heavy Mineral Sand, Sussex and Dinwiddie Counties, Virginia
… is presently operated by Iluka Resources. Heavy minerals constitute an average of 8% of the sediment, but locally reach concentrations as rich as 60%. The ore minerals, in order of decreasing concentrations, are ilmenite, rutile, and zircon, which are believed to have been derived from weathering …

Regolith and associated mineral systems of the Eucla Basin, South Australia.
… documents previous research into the heavy mineral sands (HMS) of the Eucla Basin. It presents new research designed to incorporate previous work, and to then encourage a broadening of research into the future. Specifically, this thesis is dedicated to demonstrating the importance of …

Contributions of a minerals industry cluster to sustainable development: A case study on human and social capital in Richards Bay, South Africa
… has developed with its strong connection to the minerals extraction and processing industries. Rich endowments of coal and a well-established mining sector in the country enabled the generation and supply of competitively priced electricity to energy and capital intensive processing and chemical …

The impact of natural and synthetic zeolite when used in cementitious based systems
… such as polymer rubbers and alternative mineral sands, the overall percentage emission of carbon dioxide has not decreased. Improvement of cement mortar characteristics and the reduction of carbon emissions is of keen interest to researchers and industry experts in the field of …

New Fluorescence Sensors for Critical Materials
… industry provide limited information on the minerals themselves. Measurement of the minerals is necessary as important elements can have different hosts, and the different hosts can have widely varying properties. The few mineral sensor technologies which exist tend to have long turnaround …
