Village Primary School: it is a primary school subordinate to the Central Primary School, which includes two kinds, namely "complete primary school" and "incomplete primary school". The so-called "complete primary school" refers to the school from grade one to grade six; As the name suggests, "incomplete primary school" is a primary school with incomplete grades, also known as "village school". Such schools may have only three or four grades
when the children of "incomplete primary school" reach the grade of "fault" in their own school, they need to transfer to "complete primary school" or enter the Central Primary School to continue to study, and then they may be promoted to the local junior high school. Some villages have better conditions, so that students can smoothly complete the sixth grade, while more schools belong to "incomplete primary schools"
teaching point: there are some smaller schools, which are very remote - they are not even in the village, but in the mountains. These schools may only have about ten children - even less than ten children. They may belong to different grades, but they all study in the same class
generally, there is only one teacher in a relatively small teaching point - whether it is teaching Chinese, mathematics or other subjects, it only depends on this teacher. Teaching units like this are called "teaching points", which shows that "teaching points" are more "incomplete". In the schools visited by the reporter, some have only one blackboard, the rest are only desks and chairs, and even some are not perfect
extended materials:
with the goal of opening enough and well the national curriculum, we support the construction of basic hardware facilities that can receive digital ecation resources and use them to carry out teaching, and push digital ecation resources to each teaching point through satellite transmission. Where conditions permit, investment can be further increased on the basis of central support to improve the application level of equipment and resources. Those with network access conditions should also be equipped with cameras, and a parent-child hotline should be set up by using the network to meet the communication needs of left behind children and migrant parents
the project is implemented according to the implementation mode and channel of "rural compulsory ecation weak school transformation plan". The central government implements management by objectives for all provinces (autonomous regions and municipalities), and all provinces (autonomous regions and municipalities) are responsible for the specific implementation
the Ministry of ecation is responsible for the overall coordination of the project, formulating the overall plan and schele, guiding and supervising the implementation of the project. Assist in the management and push of digital ecation resources
all provinces (autonomous regions and municipalities) are responsible for formulating specific implementation plans of local projects according to the overall plan of the Ministry of ecation, and uniformly organizing equipment bidding, procurement and installation. The organization provides digital ecation resources suitable for the actual needs of local teaching points. Organize the training of teachers' application ability. Supervise, guide and organize teaching sites to use the equipment and ecational resources to carry out teaching. Be responsible for organizing technical force to manage and maintain project equipment
according to the requirements of this circular, the ecation administrative departments of all provinces (autonomous regions and municipalities) should make overall plans for the investment of funds, make rational use of the central financial investment, strengthen the supervision of funds, and ensure that the funds are used for specific purposes. It is necessary to establish a standardized bidding mechanism and corresponding responsibility mechanism in accordance with the bidding law, government procurement law and other relevant provisions of the state, and uniformly organize equipment bidding, procurement, installation and commissioning. In order to avoid the waste of funds, the existing equipment of teaching point must be considered comprehensively in equipment bidding
we should organize the development and integration of digital ecation resources to meet the needs of local teaching materials and classroom teaching, and distribute them to each teaching point on demand. It is necessary to coordinate with the construction progress of "full coverage of digital ecational resources in teaching sites", organize and carry out teachers' application ability training in teaching sites at the same time, ensure that all teaching sites can use equipment and resources to carry out teaching, and ensure the benefit of national financial investment
it is necessary to strengthen guidance and inspection, timely find and solve various problems in the construction and application of teaching points, ensure that the project construction is carried out according to the schele requirements, and the equipment and resources are effectively used in ecation and teaching
according to the unified deployment of the province (District, city), the ecation administrative departments of all cities and counties (districts) should actively cooperate with the allocation of teaching equipment, and take the county as the unit, give full play to the role of the central school, organize the teaching points to use digital equipment and ecational resources to carry out teaching, and the districts and counties with conditions should graally realize the synchronous teaching between the teaching points and the central school
if the content is relatively low, such as only a few grams of tons or more than ten grams of tons, heap leaching method can be generally used; Need to use highly toxic sodium cyanide, replace gold with zinc wire
if the content is high, it can be seen by the naked eye, washed, dissolved in aqua regia, or burned at high temperature with borax...
if the reserves are large, it can be put on the machine, and there are many ways to electrolysis.
There are three differences between Central Primary School and general primary school: definition, teachers and emphasis
1. Different definitions
Central Primary School refers to the only primary school in a town. General primary schools refer to public primary schools in some small cities. The hardware facilities and Teacher Allocation of central primary schools are more than those of general primary schools
2. Different teachers
ordinary teachers have higher requirements than central primary school teachers. Because in order to achieve a characteristic teaching method in experimental primary school, teachers need more learning and higher requirements
3. Different emphasis
the teaching and extracurricular facilities of central primary schools are generally better, and the after-school activities are rich. Ordinary primary schools hope to be more professional in teaching and pay attention to learning< br />
these are all government investment.
it is inevitable that the class shrinkage of the village primary schools is inevitable.
thank you for your efforts for the village primary schools
the raw material of 6969 titanium concentrator is iron tailings. The methods of titanium separation include gravity separation, magnetic separation, electric separation and flotation
1292 there are several technological processes for titanium separation in instry: gravity separation and electric separation, in which the low density gangue or waste rock minerals are discarded first by gravity separation, and the coarse concentrate obtained is used for electric separation to obtain ilmenite concentrate. For sulfur-containing ores, it is necessary to remove sulfide minerals by flotation before electric separation. Gravity separation, magnetic separation and flotation process. At first, the selected materials are classified, the coarse particles are treated by gravity separation and magnetic separation, and the fine particles are treated by flotation to obtain titanium concentrate. Coarse gravity separation, electric separation, fine magnetic separation and flotation process. The characteristics of the process are that the selected materials are divided into coarse and fine parts, and the coarse particles are treated by gravity separation and electric separation; Fine particles are roughened by magnetic separation, and then fine titanium concentrate is obtained by flotation. Single flotation or magnetic separation. Flotation process. For ilmenite with fine particle size, titanium concentrate can be directly obtained by flotation after grinding and iron separation, or the wet high intensity magnetic separator can be used as roughing equipment, and then the magnetic concentrate can be recovered by flotation. Single flotation or magnetic separation. Flotation process is relatively simple, easy to operate and manage, but the use of flotation Yao agent will increase the cost of mineral processing
Complete primary school refers to the school with primary school and senior primary school, that is to say, the whole primary school stage, which is called "complete primary school", referred to as "complete primary school". After the implementation of "universal nine-year compulsory ecation" in China, the establishment of rural primary schools has become the basic standard. Primary schools in counties and cities above are generally complete, so they are no longer marked after the 1960s, while the completion of rural primary schools is still a sign of ecation popularization

classification of primary schools:
primary school
primary school refers to the ecation stage from grade one to grade four. Those who have passed the fourth grade will have a "junior high school" degree. In the 1970s, primary schools were generally established in underdeveloped rural areas of China. Rural schools in many areas are "one school, one teacher, one classroom, one class" junior primary school compound class. One teacher covers all the courses in four grades. Primary and secondary ecation is of great significance to the elimination of illiteracy
The full name of senior primary school is "senior primary school". The fifth and sixth grades of primary school are called "senior grades". Those who have completed the senior grade and passed the examination will obtain a high school ecation. Before 1949, senior primary schools were not common in Chinacomplete primary school
a school with primary and advanced primary schools is called "complete primary school", referred to as "complete primary school". After the implementation of "universal nine-year compulsory ecation" in China, the establishment of rural primary schools has become the basic standard. Primary schools in counties and cities above are generally complete, so they are no longer marked after the 1960s, while the completion of rural primary schools is still a sign of ecation popularization
