Roll Crushers

Progress in Roll-Crushing. BY C. Q. Payne, New York, N. Y. On the right, a Roll Crushers is shown in a sectional elevation of the A-C single-roll crusher while here below is a cutaway view of the machine, with hopper and part of the near side frame removed to show the crushing chamber. The moving elements of the machine consist of the roll, with its supporting shaft and driving …

Gravity Spiral Concentrator Working Principle

Spiral concentrators will tolerate minor feed variations without requiring adjustment. Spiral concentrators, like cone concentrators, are efficient, low-maintenance units that should be considered for any large-scale gravity separation system. The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).

Uranium Mining in Australia

Operating Mines. The Ranger mine. During 1988 the Olympic Dam project, then a joint venture of Western Mining Corporation and BP Minerals, commenced operations about 560 km north of Adelaide, in an arid part of South Australia. The massive deposit is underground, some 350 metres below the surface, and is the largest known uranium orebody in the world.

Gold Smelting & Metal Melting Furnaces & Equipment

Smelting Furnace of Iron Ore Laboratory-scale experiments showed that pig irons and steels of acceptable grade can be made by arc-furnace methods from east Texas siliceous ores containing less than 25 percent iron. Under highly reducing conditions, 97 to 99 percent of the iron in the ore was recovered as pig iron. Small quantities of limestone, the minimum limited only by …

Graphite stocks on the ASX: The Ultimate Guide

Metallurgical test work on the ore categorised 44% of the ore between large and super jumbo flake size. The test work also produced a 96% total graphite carbon concentrate using a simple conventional flowsheet. A concept study is underway and due to finish in the next quarter and comprises 1,400m of diamond drilling data.


Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

Ore Reserve Estimation Method

In general, however, developed ore is restricted to ore already broken in the stopes plus ore exposed on four sides—that is, ore that actually can be measured. Of course, if the exposed faces of a block of ore are far apart, an assumption is necessary regarding the continuity of ore between them, and the accuracy of the result again depends ...


Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such …

Metallurgist & Mineral Processing Engineer

The primary strengths of our metallurgists are in Grinding and Froth Flotation Systems in which we: Evaluate process and ore resource. Prioritize problems. Evaluate resources available to resolve issues. The never-ending pursuit of process stability. Implement incremental changes, one at a time, towards improving stability and production targets.


Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air.Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly …


The IsaMill™ has real-world success in 133 metalliferous installations across 21 countries. It's the world's only horizontal fine-grinding mill, so it avoids short-circuits, is highly efficient and gives the highest availability.

Froth Flotation Process

"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are …

Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl(Si2O 5) 2, lepidolite K(Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl(SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.
