Location of the major mineral sand provinces in Australia (modified from Pownceby, Sparrow, and Fisher-White, 2008)
Source publication
Almost all Australian mineral sand deposits are placer deposits, with the major commercial deposits located in four provinces along the east, west, and south coasts and in ancient basins in the southeast of the country. The development of new technology for mineral separation and its adaption to changes in the mineralogy of the deposits are discuss...

... in Australia containing the major commercial deposits of mineral sands are shown in Figure 1. Mining of these alluvial mineral sand deposits is done either dry, with earthmoving equipment to excavate and transport the sand, or wet, using dredging techniques when the ground conditions are suitable and access to water is not a problem. ...

... Ilmenite may incorporate Mg, Al, Cr and Mn within its structure through substitution with Fe 2+ . The Cr content in ilmenite is critical, as variations of up to ~1-2 % may be deemed unsuitable for processing (e.g., Australian mineral sands - Pownceby et al., 2020). Additionally, the alteration of ilmenite results in the formation new solid-solution phases such as pseudorutile and leucoxene. ...
Electron probe microanalysis (EPMA) is a well-known electron beam analytical technique
capable of providing quantitative elemental compositional information on solid materials.
Within the applied mineralogy and mineral processing sector, accurate chemical
compositions of ore minerals and/or phases are important for downstream mineral
processing and profitable metal recovery. This paper briefly examines current applications
of the EPMA technique, which has shifted according to market trends within the mining
and metal industry. Specific commodity types have seen an increase in economic relevance,
requiring routine or non-routine analytical procedures. For example, the evaluation of
polyphase, non-stoichiometric rare-earth oxides, heavy minerals, and kimberlite indicator
minerals are commonplace. The exploitation of increasingly complex, lower grade ores has
also become necessary, often requiring detection limits down to trace levels. Finally, the
future outlook of the EPMA technique is briefly discussed with respect to recent
innovations and their possible application in industry.
... The problems of determining the parameters of effective technological schemes of hydromechanized method of mineral mining from the open pits and technogenic formations are analyzed in papers [29], [30]; but there is still no solution for a problem of determining the influence of secondary raw material use on the indices of land capacity of mining. Papers [31], [32] deal with the increasing efficiency of the placer deposit development. Despite the fact that the issue of resource saving in these papers is of high priority, the research results do not take into account handling the enclosing rocks of titanium-zirconium ores. ...
Purpose. The present paper aims to develop methodological principles for the selection of effective parameters of resource-saving technologies while developing water-bearing titanium-zirconium deposits basing on the complex of analytical studies. Methods. The paper applies a complex of research methods: analytical – to analyze and generalize the main differences of the development technology for water-bearing placer deposits and problem statement; technical-economic analysis for identifying the effect of a resource-saving technology on the indices of land use of the open-pit mining and involvement of associate raw materials in the economic activity; forecasting – to determine the influence on complex development of a titanium-zirconium deposit on the operating parameters of the regional nonmetallic raw material open pits. Findings. Effective trends in using the associate raw materials located in the enclosing and overburden rocks of a titanium-zirconium deposit are identified. Key differences between the technologies of associate raw material mining from the overburden rocks and their recovery from the enclosing rocks while mineral mining are defined. Predictive influence of a resource-saving technology of the development of titanium-zirconium deposits on the extraction of building materials from the regional nonmetallic open pits is specified. Volumes of possible associate raw material mining while developing the Motronivskyi GZK open pit during its operation are determined. Originality. New dependences of a land capacity coefficient while mining nonmetallic raw material in the region, prime cost of ore development as well as number of open pits for sand and clay production in the region on the volumes of involved associate raw material of the titanium-zirconium open pits are identified. Practical implications. A structural-logical scheme is elaborated for the selection of a resource-saving technology while operating open pits for the development of titanium-zirconium deposits.
