concentration plant
1.The exploratory experiment of cyanide-free separating technology of lead-zinc in the slime for a concentration plant had been carried out.
2.The experimental study and production operation condition for the application of automatic control of grinding and classification in Midi concentration plant were introduced.
3.In 1958, Ganzhou Concentration Plant was established and started its production. After 1963, tungstic acid, APT, W powder, WC powder and cemented carbide could be produced too.
5.The axillary bud on young shoot of Barbados nut was used as explants,adding different concentration of plant hormone combinations(6-BA and IBA) on minimal medium(MS),to carry out buds inducing and multiplication culture.
6.Different inducer,inducing method and inducing concentration have great effect to plant acquired resistance.
7.The arsenic concentration of this well water was 0.6rag/L, which was 15 times as great as the maximal permissible concentration of drinking water, In the plant the morbidity of endemic chronic arseni cism was 44.6 percent.
8.Having brownish acidic waters, a high concentration of humic matter, and a small plant population. Used of a lake or pond.
9.The results were following:①Lower concentration(0.01 g/mL) of hot pepper plant aqueous extract has strong stimulating effect on the seed germination rate,germination index,seedling root length and shoot length of Chinese cabbage and lettuce;
10.The dehydration and concentration facilities at Lakeview process up to 15 million pounds of fresh plant material per year.
