Flotation machine is the most important equipment in the process of flotation. In addition to the reagents‚ the technological process‚ the performance of the flotation machine has considerable influence on flotation effect. Flotation machine can be divided into: mechanical agitation type flotation machine‚ inflatable flotation machine‚ the hybrid flotation machine or air mixing type flotation machine‚ air- releasing flotation machine. (1) The mechanical agitation type flotation machine

* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away
