Machine-made sand "flies" to an altitude of 270 meters

Reduce costs for key projects in the Guangdong-Hong Kong-Macao Greater Bay Area

Recently, the control project of the Zhongshan East Outer Ring Expressway, a key project in the Guangdong-Hong Kong-Macao Greater Bay Area, the south main tower of the Xiangshan Bridge, was successfully capped, marking a key step towards the opening of the double-deck steel truss cable-stayed bridge with the largest span and the widest bridge deck in China. The main span of Xiangshan Bridge is 880 meters, the tower is 270 meters high, equivalent to a 90-story building, and the upper and lower double decks are two-way 8 lanes, with the characteristics of super large span, super wide bridge deck, super high cable tower, super heavy load and super large cable force.

In order to solve the technical problems of high-tower pumping machine-made sand concrete, the project department finally selected high-quality machine-made sand as raw material after many tests and comparisons, and determined the optimal mix ratio by optimizing the formula of superplasticizer and comparing and selecting the combination of rubber materials, so that its working performance, strength and appearance meet the requirements. The first trial of machine-made sand on the ultra-high cable tower of Xiangshan Bridge has expanded the application range of machine-made sand, and also effectively reduced production costs.

A large gold mine was discovered in Bayannur, Inner Mongolia

The estimated potential value is $17 billion

The explorers of Tuguzhige Gold Mine in Urad Zhongqi recently discovered a large-scale gold mine in geological exploration, with a resource of 38 tons and an estimated potential value of about 17 billion yuan, which is another achievement of deep exploration of Bayannur Gold Mine in recent years.

The Tuguzhige gold mine, located near the town of Ganqimaodu, has completed 57 drilling operations this year, with a drilling workload of 27,14110m, exploration area 252km²。

This gold exploration will provide a geological basis for the rational development and utilization of mineral resources and the change of mining scope, and provide resource guarantee for extending the service life of the mine. There are 68 kinds of mineral deposits such as coal, oil, iron, lead and zinc, silica, crystalline graphite, granite and other minerals in the mineral resources of Urad Zhongqi. In particular, the proven reserves are 143 tons, the prospective reserves are 300 tons, and the annual output is nearly 48 tons, is the top ten counties and cities in the country;The reserves of crystalline graphite minerals exceed 100 million tons, which need to be developed urgently, and the potential economic value of mineral resources is more than 400 billion yuan.

Intent to jump on the "cobalt car"?

Chile aims to be among the world's top three cobalt producers

Chile, the world's largest copper producer, has unveiled an ambitious plan to become one of the world's top three cobalt producers while boosting its lagging copper production. Copper is a key ingredient in the manufacture of electric vehicles, while cobalt, also known as "blue gold", is a by-product of copper and nickel ore processing.

Chile is already the world's second largest producer of lithium mines, and if it can successfully produce cobalt metal, Chile is expected to become a major country for battery metals. It is reported that almost all lithium-ion batteries currently use cobalt metal, and lithium-ion batteries in turn power mobile phones, laptops, tablets, Bluetooth devices and even electric toothbrushes.
