Mineral sands processing has been at the heart of what we do and who we are for over 80 years. Initially we focussed on developing and optimising our own operations, today we assist our clients to build efficient and sustainable operations worldwide. You could say that Mineral sands processing is in our DNA."
The processing of silica sand prior to glass synthesis generally involves washing with water, physical screening (size and magnetic separation) and chemical treatments.
(2011). The flowsheet described above is commonly referred to as the "RKEF process" (Walker et al., 2009) due to its use of rotary kilns (RK) and electric furnaces (EF). Typical industrial data was given by Warner et al. (2006) and part of this is shown below for several smelters. Table 1 – Typical industrial data from Warner et al. (2006)
A process flowsheet was developed according to the optimum test results. The importance of this research is that it is the first example of developing a flowsheet for the beneficiation of sulphide and oxide type nickel mineralization observed together in chromite ore deposits. Keywords:
process flowsheet designs for new and existing mineral processing circuits. We are a certified quarantine station and our Australian test facility has the capacity to work with samples of any size. At this facility we can quantify mineral characteristics and processing options for a wide range of minerals including mineral sands, coal, iron ore,
Often the Silica is limited to 1.2% with penalties starting at 1.0% SiO2. These limitations on grade and impurities require extremely close mill control, particularly through flotation where selectivity and high recovery is essential. ...

The problem involved in Manganese Ore Processing deals with the production of acceptable specification grades of manganese concentrates at a maximum recovery of the total manganese from ores having variable characteristics. The flowsheet provides for both gravity and flotation with a maximum recovery of the manganese …
Sink and Float separation process. One of the first commercial applications of a medium to effect a sink-float separation used a fine silica sand suspension for treating anthracite coal and is known as the "Chance" process. The method used for cleaning the medium is decantation which limits the minimum grain size of the solid in the suspension.
Drawing on our extensive experience in mineral sands, the engineering and metallurgical team developed a process flowsheet to deliver high-grade Silica Sand to meet CFSM's specific requirements. Mineral Technologies also assisted CFSM with the design and operation of the product slurry pipeline; delivering the silica product to the stacker ...
Value, lump, containing not less than 85% calcium fluoride and not over 5% silica, $25 to $35 per ton. Best quality, for manufacture of hydrofluoric acid, $50 per ton. Fluorspar is found generally in veins, in gneiss, slate, limestone, crystalline limestone, and sandstone; often as gangue of metal ores, particularly of lead ores.

To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is …
1.2 Zircon structure. Zircon is a mineral that is an orthosilicate accessory. Its chemical formula is ZrSiO 4 (Z = 4) with the space group I 4 1 / amd.The zircon structure is made up of chains of consecutive, edge-shared SiO 4 and ZrO 8 polyhedra that pass along the c axis. The structure is rather wide; it incorporates "channels" of evidently vacant …
Two studies have investigated EC for dissolved silica removal, one as part of a dewatering process (Bayat et al., 2006) and one as a pretreatment for reverse osmosis (Den and Huang, 2008). However ...

Our team will determine the optimal and most capital efficient flowsheet option – incorporating a simplified process circuit, that will provide the highest overall recoveries with a consistent product grade, ensuring …
The optimal process flowsheet is selected after analysing the results of a detailed testwork program which evaluates the relative merits of each method. Another factor that contributes to the complexity of processing gold ores is the presence of adsorption-active substances that trap dissolved gold and carry it with the tailings, i.e. 'preg ...

Graphite is an important industrial mineral. Two types occur in nature, crystalline and amorphus. Crystalline graphite is used principally for crucibles and shaped structures. Amorphus graphite is used extensively in the steel and lubrication industries. In many deposits the two types grade into each other and the ore is of such low grade that …
