The remaining 72% comes from projects where silver is a by-product of mining other metals, such as copper, lead and zinc. 2 As expected, the revenues of firms focused on primary silver production tend to be much more impacted by silver prices than firms that produce it as a by-product.

"By-product" is thoroughly outmoded in modern English, so no matter what old dictionaries say, eliminate the hyphen. Common examples: coal byproducts, peanut byproducts, petroleum byproducts, soybean byproducts, byproducts of ore processing. In the latter case, the primary ores for copper & nickel (such as in Ontario) yield byproducts of silver ...

Answer (1 of 3): First, iron ore processing includes very little in the way of collateral byproducts of value. By stipulating "the byproduct" you limit the choices to one. the question might have asked "What are some of the by-products of .." but I suspect that "byproducts" were not what you we...

Silver can also be found as a byproduct of mining lead, zinc and copper. Nearly half of silver mined today is extracted when processing other kinds of ore.

The definition in Section 11e.(2) is the tailings or wastes produced by the extraction or concentration of uranium or thorium from any ore processed primarily for its source material content. See Uranium Recovery for more information on 11e.(2) byproduct material.

Extraction and Refining. Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore.

Mining and Refining – Bauxite Residue Management Bauxite residue is a by-product of the Bayer Process. It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the … »More detailed

The by-product In mining, subsidiary material worked from ore deposits in which other materials are dominant. 2. Water There are rivers and waterways that are now polluted due to human activities. People tend to think that no one will be harmed if they throw waste in our waterways.

What Happens To The By-Products? Most of the byproducts like the slag and scrap iron are recycled and used for a variety of purposes like the production of photographic chemicals, phenol, cutting oils, antiseptics and more. The iron manufacturing factories out there thus require a regular supply of ore to maintain their revenue.

The largest waste product generated in bauxite refining is the tailings (ore refuse) called "red mud." A refinery produces about the same amount of red mud as it does alumina (in terms of dry weight).

The ore samples with the fluxes are then added to a crucible, placed in a Assay Furnace, which has been pre-heated to 2,000 deg F, and left for a predetermined time, to melt or "fuse" the contents of the crucible. Then, the crucibles are removed from the assay furnace, the molten slag is carefully poured from the crucible, into a cast iron or ...

a natural resource that cannot be replaced when used up; like gas, oil, and minerals like copper and iron ore Pollution when the environment is tainted with the by-products of human actions

When hydrogen is used instead of coke to remove the oxygen from iron ore, the by-product is water rather than carbon dioxide. And when hydrogen is produced using renewable sources, it …

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...

If a company obtains two salable products from the refining of one ore, the refining process should be accounted for as a(n) a. mixed cost process. b. joint process. c. extractive process. d. reduction process. 2. Joint costs are allocated to joint products to. a. …

Bauxite is the ore comprised of hydrus aluminum oxide, in one or so of its mineral forms. A lot of Bauxite ends as metalic aluminum. Aluminum is a highly refined and man made product…

A by-product or byproduct is a secondary product derived from a production process, manufacturing process or chemical reaction; it is not the primary product or service being produced.. A by-product can be useful and marketable or it can be considered waste: for example, bran, which is a byproduct of the milling of wheat into refined flour, is sometimes composted or burned for disposal, but in ...

Ore - A mixture of ore minerals and gangue from which at least one of the metals can be extracted at a profit. Ore pass - Vertical or inclined passage for the downward transfer of ore connecting a level with the hoisting shaft or a lower level. Orebody - A natural concentration of valuable material that can be extracted and sold at a profit.

Slag is the by-product of smelting ore to purify metals. In nature, the ores of metals are found in impure states, often oxidized and mixed in with silicates or other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be …

Secondary product of less commercial value produced along with the principal product For example, corn gluten feed is a byproduct of corn milling to produce sweetners The preferred term is coproduct because it implies that the secondary product is also valuable

The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.) Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil …

The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product. This molten iron product can be cast into iron products, but is most often used as a feedstock for steel production. Blast furnace slag is a nonmetallic coproduct produced in the process.

Mercury - The main ore is the sulfide, cinnabar. Molybdenum - The primary ore mineral is molybdenite. Nickel - The primary nickel ores are pentlandite, nickel bearing pyrrhotite and a weathering product, garnierite (a mixture of népouite, pecoraite and willemseite).

The most important lead ore is galena (PbS). Other important ores, such as cerrusite (PbCO 3) and anglesite (PbSO 4), may be regarded as weathered products of galena and are usually found nearer the surface. The primary manufacture of lead involves three stages: a) ore concentration b) smelting c) refining (a) Ore concentration

The effects of post-ore metamorphism and deformation on trace element concentrations in sulfides have recently received increasing attention.
