摘要:
Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.

A limestone purification method is provided to execute a sorting process of impure minerals by using a collector such as thiophosphate, xanthate, dithiophosphate, or the mixture of dithiophosphate and thiocarbamate and to obtain limestone of high whiteness by removing color impure minerals from raw limestone of low whiteness. A limestone purification method comprises the steps of: making crushed materials by firstly breaking raw limestone; making powdered samples by secondly breaking the crushed materials; making an ore-bearing solution by suspending the powdered samples in a solution and grinding the powdered samples; and injecting a frothing agent and a collector using one of thiophosphate, xanthate, dithiophosphate, and the mixture of dithiophosphate and thiocarbamate, into the ore-bearing solution and then, floating and sorting the powdered samples to remove color impurities including at least one of quartz, pyrite, oxide, and muscovite contained in limestone.

PURPOSE: A collecting method of valuable resources from iron-making byproducts is provided to obtain kish graphite from iron-making dust or slag wasted after iron-making processes. CONSTITUTION: A collecting method of valuable resources from iron-making byproducts comprises the following steps: separating the iron-making byproducts into first byproducts and second byproducts containing different contents of calcium oxide(S10); obtaining headings containing kish graphite from the first byproduct having the relatively low content of calcium oxide by the floatation(S20); grinding the headings, and applying the supersonic vibration to the heading; and acid-processing the headings. The separation process includes a step of grain-size separating the iron-making byproducts using a 5-15 mesh sieve and a 65-150 mesh sieve. The first byproducts contain 1-10wt% of calcium oxide.
