Froth flotation
Flotation processes are described in ancient Greek and Persian literature. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven workplace applications, especially in Broken Hill, Australia, that brought the technological innovation kProblem: A copper ore initially contains 2.09% Cu. After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of 1 Froth Flotation Fundamental Principles

Froth Flotation of Copper and Copper Compounds from Fine
This article presents an approach to recover Cu of fine fractions < 0.2 mm by froth flotation. Several collector regimes are screened and flotation parameters are Froth Flotation. The froth flotation process is commonly employed for the selective separation of a mineral species from a liquid–solid suspension of both A concentration of 25–30% is suitable for economical smelting of copper.

Minerals Free Full-Text A Review on Froth Washing in Flotation
In the attempt to process lower-grade ores, mineral flotation has taken centre stage as the preferred recovery route. However, in many instances, the froth product does not have a high grade due to the entrainment of gangue minerals. Industry has solved this challenge by introducing froth washing mechanisms. Clean wash water is introduced Fault condition detection for sulfur flotation process based on texture unit distribution [J]. Computing Technology and Automation, 2013, 32(1): 28–31.

Fundamentals of froth flotation SpringerLink
Froth flotation technology has been around for about 150 years. The first true flotation process was described by the Bessel brothers in a patent from 1877 [].Although the brothers Adolph and August co-owned a factory in Dresden, it appears that Adolph (28 September 1835, Wunstorf—12 July 1886, Dresden) was actually the Deep learning is a subset of machine learning that uses artificial neural networks for extracting high-level features from image data. In the present study, a soft sensor is proposed for the prediction of the flotation performance through froth features generated by the use of pre-trained convolutional neural networks.

Practically all the metallic minerals are being recovered by the flotation process and the range of nonmetallic minerals is steadily being enlarged. Flotation, or more specifically froth flotationOnly the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.
