According to statistics, the proven coal reserves in the Zhungeer coalfield in Inner Mongolia will be 26.7 billion tons. After burning, 7 billion tons of fly ash will be produced. Each ton of fly ash contains about 0.5 tons of alumina, 85 grams of gallium and 290 grams of lithium . 钪 20 grams, the value of these rare elements far exceeds the coal itself. “It is no longer a simple coal development, supported by technological innovation. Realizing the green development and recycling of energy resources is the direction of our efforts. For example, the synergistic extraction of valuable elements from fly ash has always been a world-class problem. Guo Zhaohua, deputy general manager and chief engineer of Shenhua Zhugeer Energy Comprehensive Development Co., Ltd., told the Science and Technology Daily reporter. “One-step acid-soluble process technology has many advantages such as reduction, short process flow, wide technical conditions, acid recycling, no restriction on aluminum-silicon ratio, high comprehensive utilization rate and low cost compared with traditional alkali production process. In order to achieve high-purity extraction of alumina, it is possible to achieve efficient and comprehensive utilization of resources, which can be said to be the real dry ash of fly ash." Guo Zhaohua introduced. The “one-step acid-dissolving method†uses key technologies to target high-alumina, gallium-rich, lithium-rich and bismuth-rich fly ash in the Zhungeer mining area of ​​Inner Mongolia. It is the first to reveal the synergistic extraction of aluminum, gallium, lithium and antimony in fly ash. The mechanism of the valence element. Based on this new technology, the company has developed a complete set of process technology for the comprehensive utilization of fly ash to produce high-value products such as alumina, metal gallium, lithium carbonate and cerium oxide, and has formed the first set of pulverized coal with independent intellectual property rights in the world. The gray acid method synergistically extracts the high value of valuable elements and utilizes the process technology and equipment. This achievement has been authorized by the United States, Japan, Russia, Australia, South Africa, South Korea, Canada and other countries to PCT 4, national patents 112, including 70 invention patents; published 84 papers, published a monograph. This core technology is supported by the new model of industrialization and comprehensive utilization of coal-based associated resources of products such as fly ash-aluminum-gallium-lithium-bismuth. Taking “the demonstration production line of high-aluminum fly ash comprehensive utilization industrialization in Shenhua Zhungeer Mining Area†as an example, the realization of high-value industrialization of valuable elements of fly ash will effectively solve the shortage of bauxite resources and high dependence on foreign countries. Strategic security issues. “Our new technology provides a new way to use high-aluminum coal, low-grade bauxite and other resources in high-value utilization while solving the problem of dust pollution. In short, it has achieved a sacrifice in coal mining and exchanged more The environmental protection of the area is of great significance for the protection of green hills in the bauxite area,†said Guo Zhaohua. For the meat marinating solution we refer to meat tenderizer, Saline mixer, Saline injector(brine injection systems), vacuum massage tumbler.
While vacuum tumbler makes meat rolled in the drum under vacuum condition, similar to pulmonary respiration (make product to inflation and shrink alternatively). It makes meat salted evenly, increases the adhesive quality and taste and ensures the freshness of meat.

Saline injector can evenly inject the brine and salt auxiliary materials into the meat blocks, which can shorten the pickling time and greatly enhance the taste and yield of the meat products. The machine can be adjusted with stepping rate, stepping distance, injecting interval and injection pressure according to the technological requirements. Then the brine and salt auxiliary materials can be injected into the meat evenly and continually to reach the optimal effects.
One-step acid dissolution method: dry the valuable elements of fly ash
Recently, located in the Ordos City, Inner Mongolia Shenhua Zhungeer high aluminum powder coal ash comprehensive utilization of industrial pilot production line began running toward the annual "fly ash consumption of 300,000 tons, 125,000 tons of alumina production," the goal. This time project core technology of "acid digestion step," the official of production-based, China Nonferrous Metal Industry Association and the China Coal Industry Association to make the technology innovations such identification and evaluation: home and abroad, reached the international advanced level.
