- LECTURE I.
- The letter is to the following effect:—
- LECTURE II.
- Copper in the metallic form is employed for three classes of work:—
- Typical analysis of such plates show—
- The average test on a number of plates gave—
- TABLE III.—INFLUENCE OF IMPURITIES ON THE ELECTRICAL CONDUCTIVITY.
- Oxygen 0·53 per cent. = 4·7 per cent. Cu_{2}O.]
- LECTURE III.
- A number of unrefined metallic products met with in practice include:—
- They are best classified under three groups:—
- TABLE IV.—ANALYSES OF VARIOUS COMMERCIAL COPPERS.
- The Lake Superior copper occurs in three formations:—
- Other important sulphides include:—
- Other oxidised ores include—
- LECTURE IV.
- Such preliminary treatment may include—
- These may be summarised as follows:—
- FeS + O_{2} ➡ (Fe) + SO_{2} (i.)
- Or, combining (i.) and (ii.)—
- 2ZnS + 7,O ➡ ZnO + ZnSO_{4} + SO_{2}
- The advantages possessed by the method are—
- Amongst the many grave objections to open-air roasting are—
- The advantages of this system are that—

- Its functions are:—
- B. To prevent heat losses as much as possible, it is necessary—
- A. FOR RAPIDITY OF MELTING.
- The advantages of large grate area therefore include:—
- B. THE PREVENTION OF HEAT LOSSES.
- TABLE V.—DEVELOPMENT IN SIZE OF THE REVERBERATORY FURNACE.
- The breadth of the furnace is however, limited by—
