Sorting results on minus 12 plus 2-inch Kingston ore are in table 15. Copper recovery ranged from 47.0 pct for barren feed assaying 0.13 pct copper to 96. 8 pct for intermediate feed assaying 4.87 pct copper. The plot of copper recovery versus feed grade in figure 10 shows a trend for recovery to increase with feed grade.

Ore grade estimation is one of the most important tasks in the design of effective strategies for the exploitation of mineral resources. In this work, we compare the accuracy of ordinary kriging with advanced machine learning techniques in the estimation of mineral grade as a function of the location in the deposit. As a case study, we analyze data from the Sarcheshmesh porphyry …

The ore taken for assay is a clean sample of copper pyrites or copper matte. Method.—The sulphur in the ore or matte is eliminated by roasting. The oxide thus formed is reduced to metallic copper by fusion with potassium cyanide (Ricketts and Miller). Apparatus.—The usual scales aud furnaces for roasting and fusion (Hessian crucibles ...

Since the Mini Flotation Pilot Plant is designed to use samples obtained from exploration campaigns, different ore zones and blends of ore zones can be tested. The amount of ore required for testing is significantly less. For example, a conventional plant may require more than 15,000 kg of ore for a 5-day campaign.

Step 1: Calculate the amount of copper in the ore. 10 tons of ore * 10% copper = 1 ton of copper. Step 2: Determine the relationship between copper in ore and concentrate. Let x be the weight of the concentrate. The amount of copper in the concentrate is 30% of x, or 0.3x tons. Step 3: Set up an equation to find the concentrate weight

Tin Ore Assay.—The ore to be smelted or assayed should be concentrated to say not less than 50 per cent, of metallic tin; though to obtain satisfactory results it should be brought nearer 70 per cent., as with ore containing less than 40 to 50 per cent, of metal there will be a considerable loss both in the assaying and in the smelting.

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.
