Not illustrated. 1920 Excerpt: ...capacity of the slime charge and its density as determined by specific gravity test. Specific gravity may be explained as the ratio between the weight of a given substance and the weight of the volume of distilled water at 4 degrees C. displaced by it. The first requisite is to find the specific gravity of the dry ore-pulp. For this purpose dry some of the powdered material over a water bath or at a temperature not exceeding 100 deg. C. (212 F.), and at once weigh up carefully 250 grams and place in a dry litre measuring flask which has been previously weighed and the weight recorded. Then add about 500 cc of distilled water and mix well. The dry ore nearly always contains a large quantity of air adhering to the particles which is very difficult to detach and therefore Clennell1 recommends immersing the flask in boiling water and keeping it at that temperature for from one to two hours in order to expel all the air. It is then cooled, and distilled water added up to the mark, after which the flask with contents is weighed and the weight of the empty flask deducted, the object being to ascertain the weight of the water which has been displaced by the ore. To do this the weight of a similar volume of distilled water 1 The Cyanide Handbook, page 557 (Second Edition). must be known. A litre flask contains nominally 1000 grams of water but it is better to empty the ore pulp out of the flask and after washing well to refill with distilled water at the same temperature as was the water used for mixing with the ore sample, and after drying the exterior of the flask to weigh carefully. This figure less the recorded weight of the dry flask is then compared with the weight of the same volume of the ore-and-water mixture previously found. Let a = weight of dry ore take...
