Dredge Mining, Dredging, Mining Techniques, Gold Mining ...

Suction dredges are essentially underwater vacuum cleaners. They are commonly used to pull material up from a stream bottom, run through a separation system to recover valuable minerals, and then redeposit the stream material back onto the bottom of the stream. Suction dredging is mostly done in a very dynamic environment, a natural stream or ...

Mining - Dredging Britannica

Mining - Mining - Dredging: Dredging is the underwater excavation of a placer deposit by floating equipment. Dredging systems are classified as mechanical or hydraulic, depending on the method of material transport. The bucket-ladder, or bucket-line, dredge has been the traditional placer-mining tool, and it is still the most flexible method for dredging under varying conditions.

Heavy Mineral Sand Mining with a Dredge

In the early 1940’s Humphreys Mining Company in Florida pioneered heavy mineral raining with a dredge in the United States. In 1948 Du Pont, in conjunction with Humphreys, opened their first of two mining operations recovering a titanium dioxide product in Florida. Later on in 1952 Du Pont opened their second plant, both of which used a cutterhead suction type of operation. This process is ...

Gold dredge - Wikipedia

A gold dredge is a placer mining machine that extracts gold from sand, gravel, and dirt using water and mechanical methods.. The original gold dredges were large, multi-story machines built in the first half of the 1900s. Small suction machines are currently marketed as "gold dredges" to individuals seeking gold: just offshore from the beach of Nome, Alaska, for instance.

Mineral Sands Mining – TZMI

Mineral sands deposits can be mined either wet or dry. Wet mining involves using a dredge and a floating concentrator. In this method, the floating concentrator moves along behind the dredge in the pond. In the dry mining method, earthmoving equipment is used to excavate and transport the sand. Dredging is more dependent on water availability and suitable ground conditions. Dry mining is the ...

Gold dredge - Wikipedia

The first really successful bucket dredge for gold mining was that of Choie Sew Hoy, also known as Charles Sew Hoy, in 1889. This dredge was able work river banks and flats, as well as the bottoms of streams. It became the prototype for many similar dredges, and led to a boom in gold dredging in the South Island; in Otago rivers like the Shotover River, Clutha River and the Molyneaux River ...

Moma Titanium Minerals Mine, Mozambique - Mining ...

Mining at the Moma titanium deposit. Titanium minerals at Moma are mined through dredging. The mining is carried out at Namalope flats, which was the first deposit mined. The dredges cut the ore at the surface level, causing the sand to slide into the dredge pond, which is nearly 800m-long, 300m-wide and 15m-deep. A wet concentrator plant (WCP) collects the sand pumped by the dredges. Two ...
