Publisher's Synopsis
Excerpt from Gold, Platinum, Tinstone, and Monazite in the Beach Sands on the South Coast, Queensland: With Appendixes on the Beach Sands of New South Wales, and on the Physical Properties, Sources, and Uses of Platinum
In May last a sample of brown concentrates from the auriferous sands of the South Coast was delivered at the Geological Survey Office for examination as to the presence of platinum.
A number of minute ?attened grains of a white lustrous metal were obtained by carefully panning ed the accompanying minerals. These grains were dissolved in aqua regia; the solution was evaporated to dryness, and the salt remaining was then dissolved in water. The addition of potassium iodide caused the formation of a deep rose colouration, proving the presence of platinum.
