Na 2015, onye mepụtara Cui Weihua kpughere patent: usoro maka ịkwadebe calcium carbonate dị ọcha dị ọcha site na slag ígwè.Ọ ga-ekwe omume ịme calcium carbonate dị ọcha site na slag nchara na-eji ígwè slag igwe ihe igwe kwụ ọtọ?
Dị ka China Powder Technology Network si kwuo, n'oge na-adịbeghị anya, "100000 ton carbonization method iron na steel slag comprehensive utilization industrialization display line", ọrụ nkwekọrịta nke "rejuvenating Mongolia site na sayensị na nkà na ụzụ", malitere na Baotou.Ndị Baotou Steel Group na Yukuang Environmental Protection Technology (Shanghai) Co., Ltd rụkọtara ọrụ ahụ.
