Yunnan Phosphorus ore resources to maintain reserves of 2.28 billion tons, but more than 90% of the refractory low-grade phosphate rock. According to the current mining speed of more than 10 million tons per year, the rich ore resources are maintained for less than 10 years. It is imperative to develop and utilize low-grade phosphate resources. Since 2000, we have formed a research group to carry out the research and development of medium and low grade phosphate rock ore processing technology . Through in-depth research on phosphate ore process mineralogy, synthesis and application technology of new high-efficiency flotation reagent ( collector ), mineral processing technology, etc., it has undergone laboratory test, 1,000-ton expansion test and 10,000-ton industrial In the test and other stages, the complete technology development of medium and low grade phosphate rock ore beneficiation was completed. In 2007, two sets of 2 million tons/year concentrator production line were successfully applied and achieved good economic, social and environmental benefits.

The project has studied the process properties of low-grade colloidal phosphate ore in Yunnan through process mineralogical research.
A series of new beneficiation agents and new supporting technologies have been successfully developed for the fine grain size, the inlaid mosaic, the similarity of useful minerals and gangue minerals, and the innovations are as follows: collector introducing a hydrophobic group electron withdrawing group, a hydrophilic group is introduced multi carboxyl group, the molecular polarity enhancing agents, increase the calcium chelate of magnesium ions, so that the agent has a solubility at room temperature, good dispersion , characteristics such as capture and selectivity; 2 by adjusting the pH value of the medium, a collector can meet the requirements of positive and negative flotation at the same time, and the low temperature grade phosphate rock ore is floated at room temperature for the first time; 3 Developed the “ positive floating, rough and anti-floating, one rough and one sweep ” process, and obtained qualified concentrate. The project realized the recycling process of the process and tailings wastewater, the utilization rate of return water reached over 80%, and the annual water saving reached 15 million m3. After adopting the new type of medicament, the cost of ore dressing was significantly reduced, and the environmental pollution was reduced; more than 140,000 tons of coal marked saving, energy saving effect is remarkable. The project can transform a large number of low-grade phosphate rock resources in Yunnan into high-quality phosphate concentrates through flotation processing, which can make full use of resources and effectively solve the problem of phosphorus mining and abandonment of poverty, which is the low and medium-sized low of 2.05 billion tons in Yunnan Province. The development and utilization of grade phosphate rock resources has opened up an effective way.
The process technology has guiding and demonstrating effects on the development and utilization of low-grade and difficult-to-select colloidal phosphate rock in China, and has broad application prospects.

Electric Road Bike

An electric road bike is a type of bicycle that combines the features of a traditional road bike with an electric motor and battery. It is designed for riders who want to enjoy the benefits of cycling without the physical exertion required by traditional road bikes.Electric road bikes typically have a lightweight frame and aerodynamic design,which makes them ideal for commuting, touring, and long-distance rides. They are equipped with a powerful electric motor that provides assistance when the rider needs it, such as when climbing hills or riding against strong headwinds.The electric motor is powered by a rechargeable battery that can provide anywhere from 20 to 100 miles of range,depending on the model and the terrain. The battery can be recharged using a standard electrical outlet, and it typically takes between 2 and 6 hours to fully charge.Electric road bikes come in a variety of styles,including drop-bar and flat-bar models.They are also available in different sizes and colors, so riders can choose the model that best suits their needs and preferences.
Overall, electric road bikes are a great option for riders who want to enjoy the benefits of cycling without the physical strain.They are efficient, eco-friendly, and fun to ride, making them a great investment for anyone who loves to explore the outdoors on two wheels.Electric Road Bike suit the people who like racing and want a faster and more efficient way of commuting or exercising. Electric road bikes provide an added boost of power to help riders achieve higher speeds and tackle hills with ease. They also offer a more eco-friendly alternative to traditional gas-powered vehicles.Electric road bikes are equipped with a motor and battery that provide pedal-assist, meaning the rider still has to pedal but the motor provides an extra boost of power. This allows riders to travel faster and further than they would be able to on a traditional road bike. The motor can be adjusted to provide varying levels of assistance, so riders can choose how much help they want.Electric road bikes are also lighter than traditional e-bikes, making them more agile and easier to handle. They typically have a sleek design and are built for speed, with narrow tires and a lightweight frame. This makes them perfect for racing or for riders who want to push themselves to go faster and further.Overall, electric road bikes are a great option for anyone who loves cycling and wants to take their riding to the next level. They offer a faster, more efficient way of commuting and exercising, while still providing the health benefits of traditional cycling.
