Das untenstehende Erratum zu dem in Heft 8 veröffentlichten Artikel

“ULF Cell—a Novel Design Principle for Pneumatic Froth Flotation Apparatus Utilizing Uniform Laminar Flow”

von Janez Susa und Rüdiger B. Richter wurde aus Gründen der Aktualität bereits in Heft 9 publiziert. Um den fachspezifischen Zusammenhang zu gewährleisten, stellen wir es noch einmal in das vorliegende Heft 10.

Unfortunately, errors occurred in the original article.

The presentation of the Figs. 8, 9 and 10 and the Eqs. 23 and 33d were incorrect.

The correct versions are given below.

$$Q_{in}+Q_{ca}=Q_{\text{out}}+Q_{\text{froth}}$$

(23)

$$\tau _{10}=\frac{V_{10}}{Q_{cz}}=\frac{A_{cz}\cdot h_{10}}{Q_{cz}}$$

(33d)
