Die Kaliindustrie griindet sich auf die Forderung, Ver­ arbeitung und Verwertung der Kalisalze. Hierunter ver­ steht man leichtlosliche Verbindungen des Kalis in der verschiedensten Zusammensetzung. Wie bekannt, wurden diese Salze friiher als Abraumsalze bezeichnet und auf die Halde geschiittet, bis der Chemiker Professor Mar­ chand entdeckte, daB, sie erhebliche Mengen Kali ent­ hielten. Nun hatte Liebig schon friiher die Bedeutung des Kalis fiir das Pflanzen~achstum nachgewiesen. Die Verwendung desselben zu Diingungs’zwecken war aber noch nicht in groBerem Umfange erfolgt, weil es an einer er­ giebigen Kaliquelle mangelte. Diese war mit der Ent­ deckung Marchands gefunden. Damit war die Grundlage fiir die Entwicklung der Kaliindustrie gegeben. Unsere Kalilagerstatten weisen in der Hauptsache f- gende Salzsorten auf: Steinsalz = NaCl Sylvin =KCI Karnallit = KCI + Mg Cl+ 6 H 0 2 2 Kainit = KCI + Mg 50+ 3 HP 4 Kieserit =Mg 50 +H 0. 4 2 Die Kalisalze werden zum Teil als Rohsalze unmittelbar dem Verbrauch zugefiihrt. In diesem FaIle werden sie vorher auf rein mechanischem Wege in Miihlen zerklei­ nert. Ein erheblicher Teil erfahrt erne fabrikatorische Um­ arbeitung. DemgemaB unterscheidet man R 0 h sal z e - 1 2 hierzu gehoren Kainit bzw.
