Floatation Cells

Floatation cells were used in banks or groups of ten or twelve or more depending on the mill capacity. Some cells were designed to handle slimes, some to handle high grade material and others to �clean� product from other cells. All worked in a similar fashion. The differences were in the reagents used and the speed of operation to perform the different function. As is usual in this type of operation there all sorts and sizes on the market each claiming superiority in recovery, cost effectiveness, and price. Some mines even developed their own building them on site using local materials.

Mine Whistle

All the mines in Cobalt had their whistles mounted on the headframes or hoistrooms and each had a distinctive sound. They were sounded at various times of day and also if an accident had occurred. From the sound it was known which mine whistle had blown. As far as is known this is the last remaining whistle in Cobalt. It can be seen in the Cobalt Northern Ontario Mining Museum located across the street from the Willet Green Miller Memorial Site (Site #14 on the Heritage Silver Trail).
