However, the problem of separating a small amount of chrome spinel from a large amount of ilmenite requires a different approach to that from separating chromite from siliceous gangue, which has been the main commercial focus of chromite flotation in the past.

1. Poor flotation effect and high tailing discharging loss & Solutions. This situation is owing to the substandard grinding fineness of material in the flotation machine or the dosage problem of flotation reagent. If the grinding fineness is not up to the target, the grinding fineness should be appropriately increased, which can increase the ...

This poor flotation response was attributed to adsorption of collector on the slimes and the formation of a slime coating on the chromite particles. Loss of chromite values to the slime fractions ranged from 1.5 to 8.4 percent as the desliming size increased.

in such flotation has been well demonstrated [8–10]. These researchers have considered oleate, saturated carboxylic acids and alkyl sulphates as collectors for the mineral. It is well- known that...

The critical area of concern in any chrome ore beneficiation plant is the grinding circuit followed by beneficiation circuit comprising gravity units such as wet shaking tables and spirals. The effectiveness of grinding circuit depends on the consistent feed quality. Any variation in feed reduces the performance of the subsequent unit operations.

Generally, this problem of froth flotation process has the following reasons: the ore feeding is too much, the inflating volume is too much, the middle box and the liquid level adjustment plate is blocked, the suction capacity of the suction tank is insufficient, the pressure of flushing water is too small. In these cases, the blockage of the ...

The Problem with Chromite Processing. Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding.

Guney et al., illustrate that by introducing shaking table for −1 + 0.1 mm size fraction and high-intensity wet magnetic separator (HIWMS) and column flotation for treating −0.1 mm size fraction, fine chrome particles that are present in the gravity tailings of Turkish chromite gravity plants, chrome concentrate of 45–48% Cr 2 O 3 and a ...

Chrome becomes slow and unresponsive every day1. Every single day my chrome will become very slow and unresponsive, every action takes several seconds longer than it should. It also affects Windows system in general. The chrome task manager tells me nothing useful. The processes with the highest cpu or memory usage will just be chrome icon, so ...

Flotation, which is a unit process with the potential to solve this problem, has surprisingly received little attention for this application. The literature suggests the research effort to characterise the general flotation properties of chromite (chrome spinel with high chromium content) has been extensive and a substantial amount of data is ...

Flotation concentrates derived from processing UG-2 ore are typically characterized by high chrome contents (>3 wt.%) which are not amenable to conventional PGM smelters. The net effect of high chrome, inter alia, includes increased smelting energy requirements and the reduction of effective furnace capacity.

Problem: 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 concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio

Chromite is one of the main gangue consituents of UG2 ore and it is essential that the amount of chromite reporting to the concentrate during flotation be minimised since it is detrimental to the subsequent smelting operations. It is generally considered that chromite is naturally hydrophilic and only reports to the concentrate by entrainment.

TRITHIOCARBONATES FOR PGM FLOTATION 169 Introduction An increase in the beneficiation of UG2 ore is central to Impala Platinum's strategic plan for increasing its platinum production in 2006/07. Beneficiation of this chromite rich ore, however, poses certain problems and challenges. High recovery of valuable minerals from UG2 is accompanied by

and flotation for fines. In India, at both the Sukinda and Boula-Nausahi sectors, chrome ore is mined by opencast mechanized mining methods, though a few underground mines exist which are confined to Byrapur in Karnataka and the Boula and Kathpal mines in Odisha. The overall beneficiation scenario is outlined in Figure 4.
