用红土镍矿提取镍铁主要工艺-湿法冶炼? 湿法冶炼成本主要是看酸的消耗量,如果红土矿中钙、镁等碱土耗酸成分较高的话,酸浸是不合理的,只能走氨浸。火法冶炼要看红土矿镍的品位,品位过低能耗太高也是不合理的。此外还要看产品要求是什么,低 镍铁 可以走火法,镍铁中镍含量高的话,产品熔点太高,炉窑也不好实现。如果产品要求是 金属镍 ,或者要求同时回收钴,那毫无疑问,就只能以湿法为主了。查看更多 18个回答 . 5人已关注

You should write at least 120 words and base your composition on the outline below:1、大学生难找工作,2、原因很多,3、解决的办法。 Job hunting has always been a headache for college students. Though many graduates are employed right after graduation, some are not. Most serious of all, some still have no idea where to go working even a long time after graduation. The reasons for this phenomenon are various. On the one hand, a few years ago colleges and universities enrolled so many students in popular majors, such as economy, finance and so on that the number of graduates was greater than the need in the market. On the other hand, most graduates would rather stay in large cities without suitable job to do than go to the country. I reckon this problem can be solved if both colleges and students take measures. First, they should research the market and develop special skills to suit its need. Second, students’ attitude towards employment should be changed. They should go to small cities and country. There they can also give full play to their professional knowledge. In a word, if we pay much attention, the situation can be improved. 7、考试: Directions: For this part you are allowed 30 minutes to write a composition on the topic My Views on Examinations. You should write at least 120 words and base your composition on the outline below:1、大学都用考试来衡量学生的成绩,2、考生可能带来的副作用,3、我对考试的看法。 In most colleges and universities the examination is used as a chief means of deciding whether a student succeeds or fails in mastering a particular subject. Although it does the job quite efficiently, its side effects are also enormous. To begin with, examinations lower the standards of teaching. Since teachers are often judged by examination results, they are reduced to training their students in exam techniques. No subjects can be taught successfully merely through being approached with intent to take examinations. In addition, the most undesirable effect is that examinations encourage bad study habits. As the examination score is the only criterion for his academic performance, a student is driven to memorize mechanically rather than to think creatively. In fact, few of us admit that examinations can contribute anything really important to the students’ academic development. If that is the case, why cannot we make a change and devise something more efficient and reliable than examinations? 8、读后感: Directions: For this part you are allowed 30 minutes to write a composition on the topic My Favorite Novel. You should write at least 120 words and base your composition on the outline below:1、我最喜爱的小说,2、该小说的内容,3、我为什么喜爱。 My favorite novel is Around the World in Eighty Days which is written by Jules Verne. The author was born in France and devoted himself to literature and wrote several scientific romances, which gained him the name——Father of Modern Science Fiction. This is a book of science fiction which tells us an exciting story about an English gentleman, Mr. Phileas Fogg, who makes a bet with his clubmates and manages to travel around the world in eighty days. It gives us a vivid description of the many difficulties and incidents which happen on his journey. From this story, we can see the author’s deep love for the sea, travel and adventure, which played a vital role in his life. We are also astonished and convinced by his fertile imagination and scientific and geographical knowledge. 9、难忘的人: Directions: For this part you are allowed 30 minutes to write a composition on the topic The most unforgettable Person I ever Know. You should write at least 120 words and base your composition on the outline below:1、我生活中最难忘的人是,2、为什么他(或她)令我难以忘怀,3、结论。 In my life I have met a great many people who are really worth recalling. But perhaps the most unforgettable person I ever know is my English teacher. What frequently brings back memories of my school teacher is his special qualities. First and foremost, he gave us the greatest gift a teacher can offer—an awakening of a passion for learning. He not only led us to an appreciation of the beauty and perfection of English language and literature, but also aroused our great interest in exploring something deeper in this field. Furthermore, I was attracted by his lively wit. I remember that we students always anticipated his class with great eagerness because his lecture were humorously delivered, never failing to provoke chuckles or loud laughs. Although it is nearly two years since I attended his last class, he is the talk of our old classmates, and I know part of him has already stayed in my heart. 10、论说文框架: Owing to the speedy economic development, the number of people who…has considerably increased/declined. It is universally acknowledged that … plays a crucial role in modern society. Due attention has to be paid to the issue of…. With the reform and opening-up in recent decades,people in mounting numbers have come to realize the significance of ….
