copper ores. Zinc ores contain 3 to 11 zinc, along with cadmium, copper, lead, silver and iron, and small amounts of gold, germanium, indium, and thallium. The mean Cd concentration in the zinc ores is about 220 ppm. The concentration of zinc in the recovered ore called beneficiating is done by crushing, grinding, and flotation

i. Primary Crushing coarse crushing In primary crushing, ore or run-of-mine ore up to 1 m in size is crushed down to about 10 cm and it is done in a jaw or gyratory crusher. ii. Secondary Crushing intermediate crushing In this case, ore is crushed from 10 cm to less than 1 2 cm size for this
that of the final product. e.g., each ounce of gold is the result of mining and processing about 12 tonnes of ore similarly each tone of copper comes from about 30 tonnes of ore. An estimation of metal and waste generated in processing those metallic ore and the volume of waste generation due to mining activity are given in Table 1.

Dust Dust will be emitted from roadways, stockpiles, waste areas, vehicles, conveyor belt drop-offs, crushers and classifiers. Emissions can be controlled by wetting, enclosing the process area, reducing drop heights and by the use of air filters. Rock dust may cause lung disease in exposed workers. It may also be naturally radioactive. Tailings
The recycling rate of steel in Canada is more than 65 and, since 1990, Canadian steel producers have increased the amount of scrap steel that they recycle by 263. Steels overall recycling rate is higher than that of aluminum, paper and glass combined and greater than all other metals combined including aluminum, copper, nickel,
To extract the copper from the ore, a huge quantity of water must be used and it becomes contaminated with the same pollutants as the leaching effluents. Crushing of the ore likewise produces a large amount of dust. Finally, the energy needed for copper smelting requires the use
3. Ore Transportation. Ore is transported from the mine pit by haul trucks capable of carrying up to 400 tons to either the Crushing and Grinding section of the mine Step 5 or directly to the Leach Pad Step 7. Ore transportation operations can generate particulate matter i.e., dust that contains TRI chemicals.
Ore is then collected from the piles by a reclaimer which deposits it on a conveyer belt. The conveyor belt carries the ore to crushing and screening. Ore is first screened to remove oversized material and then crushed to a uniform size and sent to the briquetting process. Fugitive dust from screening and crushing is collected by three baghouses.
Absorption Water absorption values for lead, zinc, copper and iron ore tailings are typically higher than the standard maximum limit of 1.0 percent for fine aggregate in asphalt paving mixes. 6,7 Unit Weight Iron ore tailings and taconite tailings from northern Minnesota have high unit weight values, up to as high as 2750 kgm 3 170 lbft ...

estimated to be 310 million tonnes of copper ore with an average total copper grade of 1.14 at a total copper cut-off grade of 0.30. These ore reserves are divided between 79 million tonnes of heap leach oxide ore at a grade of 1.18 total copper and The plan above shows the final project layout.
1.1.4 Disposal of overburden and waste rock In almost every project, metallic ores are buried under a layer of ordinary soil or rock called overburden or waste rock that must be moved or excavated to allow access to the metallic ore deposit. For most mining projects, the quantity of overburden generated by mining is enormous.
Manufactured Sands. On a large number of crushing operations a crusher dust is often left over as a by-product of the crushing process. Through the introduction of our custom built wet processing plants we can transform this material from a waste product into commercially valuable sand and aggregates with a wide range of applications.

ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is delivered to the crushers to be reduced in size. At this stage, much of the moisture with the ore may be
Secondary crushing. The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important. In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing.

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
