Deposit model for heavy-mineral sands in coastal environments

Individual ore deposits typically comprise at least 10 megatonnes of ore (the total size of the individual sand-silt body), whose overall heavy-mineral content is 2 to greater than 10 percent. Heavy-mineral sands deposits are relatively easy to mine because they are weakly to poorly consolidated, and they are relatively easy to process.

“Mineral Sands Deposits: their complexity and need for ...

The term “Mineral Sands” refers to sands which contain suites of minerals with high specific gravity (> 4 Specific Gravity) known as heavy minerals. Heavy minerals occurs as disseminated, associated or concentrated deposits within the sands. Found in an alluvial (old beach or river system) environment.

Heavy Mineral - an overview ScienceDirect Topics

Heavy mineral sands are extracted by dredge (Figure 8), bucket-wheel excavators or draglines, and bulldozers. The raw material is then processed, first by gravity concentrators, to remove light minerals; the concentrate is scrubbed and dried, ilmenite, leucoxene, and rutile being removed by magnetic and high-tension techniques ( Figure 9 ).

Placer deposit - Wikipedia

In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word placer, meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush.

mineral-sands

Mineral sand deposits are formed from the erosion and weathering of pre-existing igneous rocks such as granite, pegmatite and basalt. Over 60 to 200 million years the combinations of wind and water from ancient rivers and seas have leached the minerals from their past rocks and concentrated them into beach and dune deposits.
