The Multotec hydrocyclone technology range comprises hydrocyclone diameters from 25 to 1 400 mm. Most of these diameters can accommodate a range of cone angles, while different vortex finders and spigot diameters are standard for all diameters. Small diameter hydrocyclones (up to 100 mm) are manufactured mainly from polyurethane, while larger ...
Keywords: hydrocyclones, coarse material, sound, flotation, classification, classifiers, particle size, slurry, beneficiation, comminution, overflow. 1. INTRODUCTION . In the mining of metals, such as copper, the ore is commonly processed in a concentrator. The concentrator typically consists of two main functions. These are the grind circuit
The SFR system was tested in the flotation circuit at a copper-moly concentrator, and the results show that the use of the skimmer has huge potential to increase the froth recovery (Rf) of both ...
One copper concentrator reported a 3% reduction in the +65 mesh fraction in their flotation feed by placing more emphasis on their cyclone maintenance program. Conclusions The objective of the classifier in the grinding circuit is to increase the capacity of the mill and produce a compact product size distribution.
The efficiency of grinding and flotation process in copper-molybdenum processing circuit, largely affected by performance of thickeners and hydrocyclones devices. The goal of this paper is to ...
The Cavex 800CVX hydrocyclones produced a finer grind size (3.1% +100 mesh) compared with the baseline 762mm hydrocyclones – resulting in a better bulk flotation for copper/molybdenum recovery. The Cavex hydrocyclones also produced a lower fines bypass/water recovery to underflow and a lower overflow density, which …
The nature of copper slag flotation is unique due to the high temperature in the flotation pulp and high metallic copper content in the feed. Despite its great potential for valorizing slag, copper slag flotation remains challenging due to the deactivation of traditional dithiocarbonate (DTC) collectors (e.g., butyl xanthate) under high ...
The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical …

In the mining industry, hydrocyclones are mineral processing equipment used in slurry pulps to separate coarse and fine particles according to their size and density. From Wikipedia:
The system described here detects the presence of unwanted excessively coarse particles in the overflow stream of a hydrocyclone using sensors mounted to the exterior pipe surface. It provides real‐time monitoring, trending, and alarming of the coarse particle level. This enables operators to identify poorly performing hydrocyclones and take ...
A maximum recovery of copper was 88,58% while the grade was 2,88 with 32,29 copper oxide on the total massive copper under the flotation conditions: 1,15 pulp density, 10 g/t dosage collector, 10 g/t dosage frother, and 50 g/t dosage dispersant and the maximum grade 12,24 while the recovery was 47,02% under the flotation conditions: …
Author: Douglas Morris One of the most ubiquitous operations in any mine is the use of hydrocyclones (cyclones) in the comminution circuit to sort particle sizes for mineral processing. Downstream of this process is the flotation circuit, which can be adversely affected if there is an upset with cyclones. Poor cyclone performance will …

Introduction: The hydrocyclone is grading equipment that uses centrifugal force to accelerate the sedimentation of ore particles. It is mostly used for grading operations in the second stage of closed-circuit grinding, and is sometimes used for mud dehydration to obtain very fine overflow products. We can also customize multiple hydrocyclones ...
A limitation encountered when designing the copper-molybdenum flotation circuits is that the optimal conditions for flotation of copper sulfide minerals do not necessarily correspond to the ... and improves operating conditions of the pumps and tanks upstream of the hydrocyclones, thereby increasing the copper recovery while reducing …
Low copper extractions both from the slag and the slag flotation tailings indicate that sulphuric acid is not a suitable reagent for leaching these materials, at room temperature. This conclusion is in line with the study by Banza et al. (2002) where the leaching of copper smelter slag with .
Publication Date: 1983: Personal Author: Kinneberg, D. J.; Miller, J. D. Page Count: 82: Abstract: The concentration of a low-grade porphyry ore by froth flotation in a 4.7-cm-diam air-sparged hydrocyclone was investigated.
Grinding and Flotation. Fine ore at minus 19mm (¾") sizing is fed at a controlled rate into the open-circuit 2600mm x 3960mm (8'-6 x 13'-0) Hardinge rod mill at an average feed rate of 2,106 STPD or 87.75 STRH.

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …
