The Processing Equipment of Hematite Mineral Essay Example
Hematite Mineral Processing Equipment
The process of hematite mineral processing equipment consists of crushing, grinding, and classification. The specific circumstances determine the type of equipment used in the process. Let's explore the different types of hematite mineral processing equipment and their applications. Here are the various types:
- Crushing equipment: jaw crusher, impact crusher, cone crusher.
- Jaw crusher is utilized for coarse jaw breaking and sucked jaw breaking.
The text describes various types of mining equipment and sieving and grading equipment used in ground mining. It also mentions the equipment used in early hematite beneficiation process. The process involves the use of re-election process, along with equipment such as jig, centrifugal concentrator, spiral chute, spiral concentrator, and shaking table.
With the advancement in mineral flotation and magnetic
...separation processes, the low-grade ore dressing recovery is gradually being eliminated. The development of hematite mineral flotation process and high-intensity magnetic separation process, which mainly involve oxidation of paraffin wax soap flotation and the use of electromagnetic flat ring intensity magnetic separator, have significantly contributed to the sorting and recovery of valuable minerals.
Despite the unsatisfactory results of sorting its technical indicators, the hematite beneficiation process has made significant progress in recent years. The main methods used in this process include high intensity magnetic separation, using the electromagnetic pulsating high gradient magnetic separator, and anti-flotation beneficiation process represented by the Series.
The main objective of hematite mineral processing equipment is to separate weakly magnetic hematite from other minerals. This equipment is primarily utilized in two situations: when the geological concentration is higher (50%), but the
ore body is thinner or mixed with waste rock, resulting in diluted ore that can be processed by simply grinding it to reduce its particle size. In this instance, the coarse tailings are disposed of while the remaining concentrate, which has a higher geological concentration, can either undergo further processing or be directly sent for smelting in a blast furnace. This process is referred to as coarse-grained re-election.
To process hematite minerals, one option is to decrease the size of smaller red ores or mixed minerals that include weakly magnetic and strongly magnetic magnetite. This involves crushing and grinding the individual iron mineral, followed by separation via re-election or magnetic reconnection. The outcome is a high-quality concentrate called fine-grained hematite re-election.
