Ironsand is found worldwide. Although the iron mineral composition of the ironsand is mostly magnetite, the sand is usually mixed with other types of sand that washes downriver or ashore from mountainous or underwater deposits. The exact composition of the sand mixture may vary drastically even in the same geographic region. In some areas the sand may contain mostly quartz, while in others the sand may be made primarily from volcanic rock such as basalt, depending o

“The extraction for magnetite sand will simply utilize a siphon vessel or an Extraction Platform. The extracted sand will then be temporarily stored, dewatered, and separated from the non-magnetic sands on board barges. All the processes for extraction will be strictly mechanical, no chemicals will be used.
