The influence of hematite addition on the lead recovery and sulfur-fixing rates is presented in Fig. 12, which illustrates that lead recovery rose from 58% to 93%, and sulfur fixation from 60% to 97% with
2022-1-8 A feasible process for preparing lightweight building materials from the low-silicate iron tailings was developed. Various proportions of bentonite, expanded perlite and feldspar were mixed into iron tailings to serve as binder, pore former and fluxing agent, respectively. The effects of blending ratios of raw materials and firing temperatures on the final product’s properties
2022-1-19 Recycling reduces the use of natural resources by reusing materials: 94% of the natural resources used by Americans are non-renewable. Non-renewable, natural resource use has increased from 59% in 1900 and 88% in 1945. Recycling saves non-renewable resources. For example, by not recycling paper, 80% more wood will need to be harvested by 2010
