Table 1 Production indicators of selected plants in 1998
product name | Production / 10,000 t | Yield/% | grade/% | Recovery rate/% |
Raw ore | 502.89 | 100.00 | 29.12 | 100.00 |
Concentrate | 181.23 | 36.04 | 63.86 | 79.02 |
Tailings | 321.67 | 63.96 | 9.55 | 20.98 |
The produced iron concentrate has a V 2 O 5 of 0.3% and a low grade, which is used for smelting steel to extract vanadium . In recent years, fine mineral rate of 30.64 percent iron, about TFe64.09%, 79.82% recovery of iron, tailings TFe9.23%, ore TFe26.04%, iron ore in V 2 O 5 is still 0.3%.
Micro Red Dot Sights (MRDS) are compact, lightweight optical devices designed to assist shooters in aiming their firearms more accurately and quickly. These sights are a type of reflex sight, which means they utilize a red dot or similar reticle to provide an aiming point for the user. The red dot is typically projected onto a lens, creating a heads-up display that allows the shooter to focus on both the target and the reticle simultaneously.
Micro Red Dot Sights are popular because they offer several advantages over traditional iron sights:
-
Faster target acquisition: The red dot can be more easily seen and aligned with the target, allowing for quicker target acquisition compared to lining up iron sights.
-
Improved accuracy: The red dot is designed to be parallax-free, which means that it remains on target regardless of the shooter's eye position. This can lead to improved accuracy, especially for those with less experience using iron sights.
-
Better low-light performance: Red dot sights are often illuminated, making them easier to use in low-light situations compared to non-illuminated iron sights.
-
Versatility: Micro Red Dot Sights can be mounted on various firearms, such as rifles, shotguns, and handguns, making them a versatile aiming solution.
-
Compact and lightweight: As the name suggests, these sights are smaller and lighter than traditional red dot sights, making them more suitable for compact firearms or for users who prefer a minimalistic setup.
Despite their advantages, Micro Red Dot Sights are not without drawbacks. They typically have a shorter battery life than larger red dot sights and may not be as rugged or durable as some other types of sights. Additionally, they may not offer the same level of magnification as other optic types, making them less suitable for long-range shooting.
