    Other mineral resources. Offshore areas of the US may contain resources of sulfur, salt, sand and gravel, phosphate rock, manganese nodules, and heavy-mineral placer deposits. To date, none of these has been produced for commercial purposes except sulfur and salt in the Gulf of Mexico, and gold in Alaskan state waters near Nome.

  • Heavy Mineral an overview ScienceDirect Topics

    Heavy minerals like ilmenite, sillimanite, garnet, zircon, rutile, monazite, magnetite, titanium, chromite, cassiterite, , gold, and platinum-palladium have a tendency to form onshore beach and offshore placer/ocean floor deposits. Prominent deposits occurring along the coastline of countries like India (Fig. 5.21), Indonesia, Malaysia, and Australia bordering the Indian Ocean are the

  • ECONOMICS AND THE SEARCH FOR OFFSHORE HEAVY

    This examines the relative importance, in terms of a deposit's commercial status, of physical characteristics of onshore titanium-bearing heavy-mineral placer deposits, and applies these findings to the search for and evaluation of offshore deposits. Results obtained by applying statistical discriminant analysis show that the characteristics most useful for predicting a deposit's

  • Deposit model for heavy-mineral sands in coastal environments

    This report provides a descriptive model of heavy-mineral sands, which are sedimentary deposits of dense minerals that accumulate with sand, silt, and clay in coastal environments, locally forming economic concentrations of the heavy minerals. This deposit type is the main source of titanium feedstock for the titanium dioxide (TiO2) pigments industry, through recovery of the minerals ilmenite

    Coastal energy conditions are such, however, that a relative increase in heavy mineral content should be observed on the rim of, or immediately offshore from, the delta. In the light of an anomalous distribution of coarse and fine quartz sands, on the offshore shoals of the area, the hypothesis is developed that the heavy mineral
