Introduction Electrogravimetric and spectrophotometric analyses of unknown copper ore sample were completed to determine the percentage composition of copper in the sample. Electrogravimetric analysis proceeds by putting the copper from the sample into solution, then plating the copper on to an electrode to determine the change in mass. Gravimetric analysis is an important part of analytical .

Ore-grade packages are used to analyse samples that have high concentrations of pay metals. They can be used in prefeasibility, feasibility or production circumstances. As well, these methods can be used to provide over range analysis when an upper limit of an element in an exploration package is exceeded. Typically, ore-grade analyses

ASTM's copper standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of copper materials, including bronze and their alloys with other metals. These materials when in the raw form are fabricated into basic shapes like sheets, strips, plates, bars, beams, disks, rods .
W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 4 The Future. The major trend in copper smelting and converting is towards improved capture of the SO 2 that is evolved from oxidizing CuFeS 2 and other copper sulfide minerals. Improved SO 2 capture benefits the environment and the resulting H 2 SO 4 product can be used for leaching "oxide" and supergene sulfide .

Sampling is the most important procedure in arriving at the value of an ore. Improper sampling makes other procedures, including assaying, valueless, as the sample must truly represent the ore from which it is taken. Before sampling, clean fresh faces must be exposed in order to prevent the possibility of salting. Having taken a large representative sample by chiseling 3″ to 6″ wide and 1 .
1.1.1 Refer to Practice E255 for copper and copper alloys. Note 1--The selection of correct portions of material and the preparation of a representative sample from such portions are necessary prerequisites to every analysis, the analysis being of no value unless the sample actually represents the average composition of the material from which .

A sample tree experiment involves splitting at different top sizes, followed by comminution and assaying5. Figure 1 shows the sample tree flowsheet. Two ores were evaluated via this sampling technique. The first sample was a low-grade gold ore (about 5 g/t gold) mill feed sample from a South African gold mine. The particle size was 95% -12 mm.
