The history of this Ore Ida product goes back to 1953 when they took the shreds from making fries, compressed them, and started selling the output as a distinct product. Initially consumers weren't interested in the product as it was relatively inexpensive.
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. …
BFG is a by-product of the chemical reduction of iron ore in blast furnaces. It typically contains about 20–30% carbon monoxide (CO) and about 2–6% hydrogen (H 2) as combustible components, and a significant amount of inert gases with about 45–60% nitrogen (N 2), and 20–25% carbon dioxide (CO 2) (see Table 14.1).
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 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.
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

At Mt Cattlin, Galaxy mines pregmatite ore and processes it onsite to produce a spodumene concentrate and a tantalum by-product. … The spodumene product …
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.
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…
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
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 ...
Tuumaenergia: Uranium Mining in Wikipedia. ... uranium ore was recovered as a byproduct of mining ... the first radium/uranium ore was discovered in 1871 in …
"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 ...
If a company obtains two salable products from the refining of one ore, the refining process should be accounted for as a(n): A. reduction process B. depletion process C. mixed cost process D. joint process E. extractive process. A 9. The assignment of raw material costs to the major end products resulting from refining a barrel of crude oil is ...
The last product is characterized for containing small amounts of gold and silver. The treatment of these products depends on the metallurgical extractive process of lead and copper. Gold Smelting Equipment. It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time.
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
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 minerals - Mineralogical Society of America ... Lead - How Products Are Made. Therefore much lead ore is obtained as a byproduct of other metal mining, .... is cooled slightly, a zinc dross rises to the top, bringing the other metals with it. Read more.
When using Co-Product an additional task is necessary before running the standard one as WIP, variances. 3.1 Preliminary settlement of co-products; If co-products are produced in a process order, the actual costs are collected on the order header. At the end of the period, these costs can be distributed to the order items according to equivalences.
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 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 …
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 …
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
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).
Even though galena is the ore being removed and lead makes up the bulk of the product, these mines are often called "silver mines." Silver as a Constituent in Other Metals and Ores Most of the silver produced today is a byproduct of mining copper, lead, and zinc.
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.
Hematite Ore Processing Plant. Hematite ore is an important mineral resource. With 70% iron content and the large iron output capacity, hematite is the most important iron ore. To improve the comprehensive usage efficiency of hematite, hematite beneficiation …
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.
