| abstract | The invention relates to methods for producing ferrocyanides, which are used as mineral inks. The purpose of the invention is to simplify and shorten the process time, and also to reduce the cost of the method. The goal is achieved by adding to 100 mach. filtrate boiler milk 3-5 wt.h. iron sulphate (II), after which 5-8 wt.h. mixtures of iron (III) sulfate and concentrated nitric acid, taken in May. ratio of 1: 2. In addition to simplifying and shortening the process, the proposed method allows reducing the consumption of expensive iron (III) sulphate, as well as solving the issue of disposing of the harmful phosphate production waste. 4 tab. |
