As a source of titanium dioxide pigment, rutile is used in plastics, …
Ironsands are taken from the beach at Waikato North Head and reduced to an iron-rich concentrate. This is piped to the Glenbrook steel mill. There it is blended with coal from nearby Huntly and reduced to molten pig iron by smelting. Recycled steel scrap is added to the molten iron, and liquid steel is produced.

Seabed mining. Small scale offshore sand mining is an established practice in the Kaipara Harbour and Pãkiri beach. This process uses suction dredging in groundwater to extract iron sands for separation prior to exporting. This sand can then be used for construction, concrete and to replenish beaches.
The ironsand is mined by a floating cutter suction dredge. The material is then concentrated through cyclonic and magnetic separators, and stored in stockpile heaps. The area has no natural harbour and is subject to storms and waves of up to 11 m high.
The following are the main steps of the magnetic separation process in sand washing plant: Crushing: The original sand ore is preliminarily crushed through crushing equipment (such as jaw crusher, cone crusher, etc.) so that the particle size is suitable for subsequent magnetic separation equipment. Washing: Send the crushed sand ore to …
Therefore, sand mining requires special attention and regulation by the Government. The legal framework, guidelines and case law on the grant of EC for sand mining category are as follows: The EIA Notification, 2006: T his notification specifies that sand mining projects with mining lease area less than 5 ha are exempted from EC 2.

In a recent report, the scientists baptized the product of the process as "ore-sand.". In other words, they propose the idea of separating and repurposing sand-like materials from mine waste ...
When mining for ironsand from the sea bed, the iron rich sand is sucked onto the plant, where the iron is separated from the …
Silica Sand Mining introduces. Foundry silica sand is the quartz as the main mineral composition, particle size of 0.020 mm to 3.350 mm refractory particles, according to the mining and processing methods of different can be divided into artificial silica sand and sand washing, sand washing, selection of natural silica sand such as sand (flotation).
The process is simplified. The roasted ore is subject to magnetic separation after water quenching and classification. After magnetic separation, the magnetite fine powder with high iron grade, low arsenic and sulfur impurities is obtained. It is widely used for beneficiation of ores and waste residues containing weakly magnetic iron minerals.
