black iron sand mining process

Ironsand Wikipedia

The ironsand is mixed with the other sands as small grains of black or dark-blue magnetite. Sand used for mining typically had anywhere from 19% magnetite to as low as 2%. The ironsand typically had to be separated from the sand mixture.

Black Sands Processing « TCB Metals and Refining

Due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.

The History of Ironsand New Zealand Steel

Its potential for commercial use was recognised from the early days of European settlement. This black ironsand was formed 2.5 million years ago from rock deposited on the coast by volcanic activity in the Taranaki region. The sand contains mainly ironsand (titanomagnetite) and lime-soda feldspars.

The Mining Operation New Zealand Steel

Each year 1.2 to 1.4 million tonnes of ironsand is needed to produce steel at Glenbrook. To obtain this, 4 to 7 million tonnes of sand needs to be mined at the Waikato North Head site. Once the sand is mined, the titanomagnetite is separated from the sand by magnetic and gravity separation processes. No chemicals or other additives are used.

Black Sand Concentrates Gold Fever Prospecting Mining

It is usually a combination of minerals in the iron group: Hematite, Fe3o3, with a specific gravity of 5.26, an iron mineral that is non-magnetic and Magnetite, Fe3o4, with a specific gravity of 5.20, is magnetic. These black sands will weigh a third (1/3) to a fourth (1/4) the weight of gold (Au). Gold has a specific gravity of 15 to 19.3.
