Mining includes drilling and blasting loading and hauling ore and crushing to produce copper ore Processing includes grinding flotation and dewatering to produce copper concentrate which buyers pay for the copper gold and silver content Copper concentrate is PTFI s final product with value added 95%
·Before going ahead with the mining guide and ore distribution you may want to know what is called the chunk in Minecraft They look exactly like the original block but with some black dots embedded in them Quantity 20 510 coal ores per chunk Like copper ore Lapis Lazuli ore has two variants and can be found pretty easily because of
·Generation [edit edit source] The ore feature has two types ore blobs and scatter ores An ore blob is an ellipsoidal cluster of blocks In the overworld underground deposits of dirt and gravel are generated in this form followed by the more precious ores like coal copper iron gold redstone diamond emerald in mountains biomes and lapis lazuli
Figure 2 shows a typical cross section of a block model for an open pit undeveloped copper project Pit designs and mining sequences are determined by optimization algorithms which consider the

·Ridgeway Deeps was developed at a cost of A$525m by Ausenco The project involved construction of a block cave extension of the existing underground ore handling system including two new primary underground crushers development of bulk underground mining technologies such as the application of automated remote loaders and modifications to the
·The mined uranium ore is crushed and chemically treated to separate the uranium usually by the addition of acid or alkali The remaining crushed rock called tailings must be appropriately disposed of Alternatively for
Mineral processing In the ore dressing plant the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials or cases where the next step is leaching most frequently in the case of oxide ores complete liberation of the copper minerals is not always necessary; the
·Copper Mining Mining is the initial phase in the extraction process Copper ore must be extracted using either open pit or subterranean techniques Open pit mining is the most efficient technique for extracting huge quantities of material from
2 ·Ores can be smelted faster using a blast It is not efficient to mine with Silk Touch and then smelt an ore block that normally drops multiple pieces of its resource because smelting these ores yields less experience and only 1 piece of the resource Nether gold ore is the only exception as each ore block drops an average of gold nuggets even when mined with
• minimum mining block size for all other pits = 200 m x 125 m x 15 m • mining flitch height = 15 m • maximum vertical advance rate = 60 to 75 m/year The predominantly copper/molybdenum sulphide ore is amenable to conventional differential flotation processing with gold and silver recovered into the copper concentrate and also
2 ·Copper processing is a complicated process that begins with mining of the ore less than 1% copper and ends with sheets of % pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy
·Open pit mining method is one of the surface mining methods that has a traditional cone shaped excavation and is usually employed to exploit a near surface nonselective and low grade zones deposits It often results in high productivity and requires large capital investments low operating costs and good safety conditions The main topics that will
