Abstract
Inventia se refera la un procedeu pentru prepararea cianurii de argint printr-o reactie de precipitare a ionilor de argint, cu oxicianura alcalina, dintr-o solutia apoasa de azotat de argint, în mediu de acid azotic diluat, la concentratia initiala de 1...10 g/l si finala de 0,1...1 g/l, de preferinta 7...8 g/l, respectiv 0,5 g/l în intervalul de temperatura de 10...49 degree C, cu recuperarea metalului pretios din solutia muma, sub forma de iodura de argint.The invention relates to a process for the preparation of silver cyanide by a silver ion precipitation reaction with alkaline oxirane from an aqueous solution of silver nitrate in diluted nitric acid medium at the initial concentration of 1. 10 g / L and 0.1 to 1 g / l, preferably 7 to 8 g / l and 0.5 g / l in the temperature range of 10 ... 49 ° C, with the recovery of precious metal from the mum solution, in the form of silver iodide.
