Di dalam proses flotasi<\/strong>, froth serves as the most intuitive “barometer” for evaluating flotation performance. Experienced mineral processing engineers<\/a> can accurately diagnose the health of a flotation system by observing subtle changes in froth characteristics. Much like traditional Chinese medicine practitioners diagnose ailments through observation (“look, listen, ask, check”), flotation experts can quickly identify process issues by analyzing froth behavior. This article focuses on three key froth abnormality signals: “large and brittle” (indicating insufficient mineralization), “sticky and lifeless” (a sign of severe particle entrainment), and “fine and glossy” (reflecting slime interference).<\/b><\/strong> We will conduct an in-depth analysis of the problem characteristics, causal mechanisms, and countermeasures associated with these abnormal froth behaviors. Mastering these diagnostic techniques holds significant practical value for improving flotation indices and reducing reagent consumption.<\/p>\n

Abnormal Flotation Foam: Large & Brittle, Sticky & Lifeless, Fine & Glossy<\/h2>\n

<\/b>1. The Foam is “Large and Brittle.” <\/strong><\/h3>\n

– <\/b><\/strong>W<\/b><\/strong>arning light for insufficient mineralization<\/b><\/strong><\/p>\n

Features: <\/b><\/strong>The foam size is relatively large, the bubble wall is thin, almost transparent, and sometimes the reflection of the water film can be seen (the bubble diameter is greater than 3 mm, easy to break, the foam layer is thin, and the duration is short). The foam layer is volatile, with a thickness of less than 5 cm (the normal operating range is 10-30 cm), and it produces a “puff, puff” sound. It will burst quickly with a slight disturbance, and the amount of scraped concentrate is small, and the water leakage is serious. Commonly known as “big bubbles” and “flowers”.<\/p>\n

Reasons and Diagnosis<\/h4>\n

This is a typical signal of insufficient mineralization, that is, the surface of the bubble fails to attach to a sufficient amount of hydrophobic mineral particles, resulting in a sharp decrease in foam stability.<\/p>\n
