Since interference frequently occurs, some care is usually necessary. As an illustration, the following condensed procedure serves for the detection of the ferrocyanide ion in the presence of ferricyanide and thiocyanate: ....Read more

Ferrocyanide Toxicity https://www.911metallurgist.com/blog/ferrocyanide-toxicity Tue, 20 Jun 2017 13:32:53 +0000 https://www.911metallurgist.com/blog/?p=92651 It is generally agreed that the ferrocyanide ion is of a low order of oral toxicity, even in relatively large dosage. Kobert states that potassium ferrocyanide in alkaline solution is nontoxic. In Precis de Toxicologie it likewise is asserted that this salt is nonpoisonous and that it is useful as a diuretic. There is recorded ....Read more

Ferrocyanides Usage & Applications https://www.911metallurgist.com/blog/ferrocyanides-usage-applications Tue, 20 Jun 2017 13:31:12 +0000 https://www.911metallurgist.com/blog/?p=92649 Alkali metal ferrocyanides and their easily obtainable derivatives such as ferricyanides, nitroprussides, and hydroferrocyanic acid have found application in a wide variety of fields during the two centuries that they have been known. Through continued research new uses are being uncovered with increasing frequency. Most of these applications depend upon oxidation-reduction potentials, sequestering and precipitating ....Read more

Hydroferrocyanic Acid https://www.911metallurgist.com/blog/hydroferrocyanic-acid Tue, 20 Jun 2017 13:24:28 +0000 https://www.911metallurgist.com/blog/?p=92645 PHYSICAL PROPERTIES of Hydroferrocyanic Acid Hydroferrocyanic acid is most conveniently prepared by the treatment of an alkali metal ferrocyanide with a strong mineral acid. A typical preparation would involve the treatment of a saturated aqueous solution of potassium ferrocyanide with concentrated hydrochloric acid. The acid separates as a crystalline solid that may be purified further by ....Read more

Ferrocyanides https://www.911metallurgist.com/blog/ferrocyanides Mon, 05 Jun 2017 13:43:23 +0000 https://www.911metallurgist.com/blog/?p=83247 The study and use of ferrocyanides was initiated with the discovery of the pigment "Prussian Blue" by Diesbach in 1704. Thus, they are among the earliest commercial chemicals and have been produced in large quantities for many years. In the United States, American Cyanamid Company, with its ample supplies of cyanides as starting materials, has ....Read more

Slurry Flow Rate Through a Mill https://www.911metallurgist.com/blog/slurry-flow-rate-mill Tue, 30 May 2017 12:06:42 +0000 https://www.911metallurgist.com/blog/?p=92581 The factors upon which the rate of flow of the pulp through a mill depends appear not to have received extensive investigation. In an article by Anselm translated by Pearson a method for the calculation of the time of passage of cement through a ball mill was given. The basis of the method is that the ....Read more
