Notes on ore concentration by means of electro-magnetic separation

The President: Some time ago it was arranged — in fact, at last year's Council Meetings — to have some sort or a meeting and a visit when this separator was available for exhibition and tests; but owing to the situation it was found impossible to carry out this plan. A few weeks ago it was arranged that the separator was to be shown here at the Mining Exhibition in this building and, innocently enough, I suggested we should have a visit. I had no intention, when I spoke last month, of writing at an early date a further paper in connection with the one I read in 1911 on the Magnetic Separator. I was, however, called upon to make some notes. When I started to make these notes I found it was a very big subject. So if to-night the notes are somewhat disjointed, you will know it was not my intention to make the notes at this date; but to give some figures and views from all over the world regarding separators; so that one could see the different types, etc. However, time did not permit of this procedure. Now, in connection with the meeting to-night, we thought we would first have the paper read and a discussion on separators, and then, if you all agree, we would have coffee and then make a visit to the basement, where I will put some samples through, be pleased to answer any questions and do anything possible to oblige.
